????????

What have you done to investigate this problem?

What do you use for your database?
Have you got means of accessing th database outside of Hesk?
If yes, can you run a sql query against it at all or access the contents of any of the tables in the hesk database?

really need more details

If you use MySQL, there is a test script here http://www.kriyayoga.com/love_blog/post.php/781 if it helps?

I would check your username/passwords, make sure you can access it outside of Hesk, also make sure you can talk to the tables if you can access it.
I would also ensure if you are hosting the site externally, nothing has changed on your hosting company that is locking it out or check if they have made changes

yes

Another test is the hesk install script itself
I know its in the current version, cant remember the old ones
But basically backup the DB just incase
I ran it just now and on the last step, it popped up saying the tables already exist. But this proved to me that it is talking to the DB

I got this:

Well you haven't changed anything in the script and it worked fine before so the problem isn't the script, it's your MySQL or PHP (either connection between the two, or maybe your mysql username/tables are modified).
