Problem with my advanced guestbook. *Problem solved*

Hi, after a problem on my webhotels server i cant not longer use the guestbooks admin part, i can sign the guestbook as usuall and when i log in to the admin site there no problem but after i have logged in to the admin site and click on exampel easy admin i get logged out, this happend regardless whta i click on. Is the problem on the webhotel or is it anything i can do about it. This problem started after that my webhotels server had intruders from the inside that hade destroyd things on the servers, i have talked to them but i dont really get anything out of it. Or can i delete messages in the guestbook on any other way than throught the admin site?
