Getting kicked for "Wrong Signature" Error need help to fix!

[factordog 0]

I have been playing Dayz Mod for some time, and just recently i have been being kicked off every server that i play on (sometimes as soon as i enter the lobby) for wrong signature file, i have gone to the forums, and looked on the internet for a solution, ive taken a backup from my laptop and re-installed on my PC as well as whenever i try to re-install something like battle eye it will give me the error "failed to start game missing executable" (im not sure if that links in with that).

All im wanting is to be able to be stopped being kicked for wrong signature error and im not sure how to fix this issue (as now i cant play at all without getting kicked after 0-20mins of play and sometimes ends up in me dieing due to very large gun fights or something that occurs in game)

Your registry has been corrupted... just go through to yah steam, right click on OA and arma .exe, properties/ local files/ verify game cache. then run both games individually up to the menu (ensuring that you are running steam as administrator) to rewirte yah registry.

hopefully this will work... other wise you will have to delete your ARMA & OA registry before doing the above steps. Ive posted links before on how to do this, but dont have time right now to locate them. (the other posts... about 6 of them would be in people posting similiar issues, but probably under heading o "kicked from game" or similiar.
