Many of the problems you describe (like not being able to kick a user, and getting an error (RichEdit error I'm betting) ) have been fixed in the latest server versions.

Try downloading the latest version 2.0.23.15 for starters.

Secondly, if that in and of itself doesn't solve your problem, make sure that each an every person on your server who has (SA) rights is using a nice, strong passphrase. "money" "sex" or "1337" are NOT good passwords.

"T34mSp34kIsK3wl" on the other hand, would be pretty hard to "hack".

Lastly - yes, it's upsetting to have to start over, but there are several things you can do right to avoid that kind of problem. The first would be to make regular backups of your server.dbs and server.ini file. Someone hacks your server? Shut it down, restore those files, and BLAM, in 60 seconds you're right back to normal.

What you should NOT do, is start posting in a forum, half-cocked, angry at the wrong people, for problems that are, frankly, as likely to be your own as they are anyone else's.

Remember - we learn from our mistakes. The catch is, you can learn one of two things - that "it isn't my fault, so I've got nothing to learn" or "what can I do to stop this happening again".

The choice is yours.

I hope you're happy with whichever one you choose.
