Won't Open; Deleted-Reinstalled at Least 6 Times

Em Client will not open. Has been deleted/reinstalled at least 6 times! When reinstalled now - at best, says the database was not properly closed last time, will now restart.

It NEVER restarts; will not open at all. I like Em Client. Help?

PS The Above Problem:

In the beginning, received the error message below. I have tried EM Client database repair. When I run Em Client database repair - IT JUST GIVES THIS MESSAGE AGAIN. Does not repair anything.

Hello, when reinstalling, eM Client will not delete data files directory. If you want to start with clean database, please remove/rename folder c:/Documents and Settings//eM Client/
