Hi guys,
Just wanted to say I managed to fix my !!!MISSING STRING error by reinstalling both Arma 2 and OA. Then the running steam as admin fix worked correctly and I was able to install. If you are running Windows 8 and have retail Arma 2 and Steam OA, this might fix the issue for you too! Perhaps one issue which I'm not sure is DLC related or perhaps to do with my new clean install, is I now have to use the -flush command much more regularly, otherwise arma will minimize. I seem to remember reading a fix for this in the past, if anyone is able to point me in the right direction it would be appreciated. As for the DLC itself, I find it quite enjoyable. Only came across one bug so far during the civilian escort mission on Takistan - when my Humvee was hit by an IED, my troops bailed out as I repaired it, I ordered them back, but one soldier kept refusing. I noticed that he had already ran around 400m away in the time it took to fix the Humvee. I spotted him just before he walked into a minefield :( RIP Brave Czech!
I would echo the comments of others that the new Bystrica terrain looks pretty and the main campaign seems to be quite fun so far. I would agree with Johan that it seems similar in quality to PMC.
