Can't join any servers - OA missing files?

[Lurk101 10]

So about two weeks ago I came across a problem where I can't join any servers. I don't remember the original message I was given, but I tried joining friends in Takistan Life and could not. I figured it was just a problem with that MOD. Later on I tried to play just regular ARMA 2 multiplayer and still could not join any servers, my game was up to date with patches and battleye. So I uninstalled both ARMA 2 and OA and reinstalled but that came with no luck. I had mainly been playing DayZ with no problems at all and now I can't even play that, I get messages while loading the game such as - arma 2 oa addon 'dayz_anim' requires addon 'casigns2' and -no entry 'bin config.bin/cfgvehicles/house.scope' while joining the server.

I have searched both of those messages and the suggested fixes haven't worked. Verifying the integrity of the game cache for OA gives me a message that 1 file is missing and will be acquired, but it doesn't seem to. I have ARMA 2 retail and OA on steam and to me it seems that when I download OA that not everything is being downloaded. I get messages from many servers telling me that I had deleted content or files that are required to join, I haven't deleted anything so I don't know why I had that.

I have had these games for quite some time with no issues, but now I can't play online and messing around with the editor gives me with all kinds of messages depending on what I put in. I don't know what to do, following a fix for one problem just leads me to another problem and a bigger headache. I thought about buying both ARMA 2 and OA on steam through the Combined Operations pack but I don't want to spend more money on games I already have especially when it might not fix my problems.

I had the same exact problem for the longest time, it only recently started happening about 6 or 7 months ago.

I too had the retail version of A2 and the steam version of A2:OA, but recently it seems with all this controversy over DayZ its caused a HUGE amount of problems for people that use this same method, I finally cracked and just bought the steam version, which it seems to have fixed a LOT of my problems, though now im just having ONE single error come up thats constantly keeping me from playing any MP games.

Right now A2 is $13 on steam so really its not a lot to lose to fix all these problems, though now im gonna be digging around for answers to the one problem i've been having, which im suspecting has to do with BE but that doesnt entirely seem to be the case

The error I get constantly now when I join a game is "common/ca_scripts.pbo file are signed on a key not recognized by this server. To play on this server, remove listed files or install additional accepted keys" blah blah, and I get this problem with EVERY server i've ever tried to go on that i've been on in the past plenty of times, except for smaller, less known ones, @_@ so frustrating to be so close to playing my favorite game again, only to be held back by this one problem...

EDIT: Problem solved, I just removed above mentioned file and its .psign and now it works

So to summarize this, the physical copy of A2 seems to not compile properly, but I read somewhere that you have to make sure the OA files are mixed with the A2 files, so put your OA files inside your bohemia interactive/ Arma 2 Folder or something like that, either that or just buy the steam version like I did which fixed my problems, good luck brah
