PMC some files not signed by a accepted key

Hello, after i was try to go on some Server, i get the following Error message.

Files: "pmc\addons\air_.pbo", "pmc\addons\ca_pmc.pbo",

"pmc\addons\characters_pmc.pbo",

"pmc\addons\dubbingradio_pmc.pbo",

"pmc\addons\dubbing_pmc.pbo",

"pmc\addons\languagemissions_pmc.pbo", ... are not signed by a

key accepted by this server. To play on this server, remove

listed files or install additional accepted keys.

I was buy PMC on Sprocketidea yesterday include CO and BAF. I installed first ArmA 2, then ArmA 2 OA, then BAF and last PMC. On BAF and PMC there was no trouble during the installation. Hope someone can help me.

This is a known problem that has been fixed in the recent beta versions. I recommend getting the latest beta here. (Green bar at the top of the page.)

Note: When installing a beta version it will say something like "this process cannot be undone, you will need to reinstall the game" - but that is not true. Betas are installed alongside the non-beta content like mods, but with a different .exe file, and can be easily uninstalled or simply not used.

Also, starting the game from your usual desktop shortcut will not launch the beta version. You will need to use the new "Launch Arma2 OA beta" shortcut that gets created in the main game directory.

Thanks for the reply, i was try to get a solution to play on the server. So i was notice, that the Maingames came with all Updates (ArmA 2 on 1.10 and OA on 1.59). So i was think that BAF and PMC also up to date. I don't know if they was not up to date or only missing files but i was find the problem

By showing in the directory of ArmA 2 especially the PMC directory, i was notice that there are two types of Keyfiles.

*.pbo.bi.bisign and *.pbo.bi2.bisign

The PMC DLC only contains the *.pbo.bi.bisign Keys and the *.pbo.bi2.bisign Keys are completly missing. So i was try to install the 1.59 Patch including the latest PMC and BAF Patchfiles. After an error that ArmA 2 is newer then 1.09, the installation runs fine.

After the installation i was show in the directorys of PMC again. And now i was find both bisign files. And i was able to join the Server again. So maybe this files are missing or PMC was not up to date in the Sprocket Version.
