No we don't keep back-ups to my knowledge on any of our servers, the only time we take a back up is when something goes wrong.
You'll have to speak to KF via steam because I deleted all the AGS related servers from my clients after the passwords got changed on me. Sounds like a problem we had in the past I found the solution last time... Looks like it just needs to be applied again, if you get into contact with KF tell him a new R came out he may just need a re-compile.
--Please please stop questioning me about the server people I don't know any more than you do.
--Also someone let Mouldy know I just saw his PM and responded to it...
