Hi, i'm having problems with vB v2.0

I've just changed servers, made a dump and got the host to restore it using telnet. This has been successful.

Now i've reinstalled vB quite a few times and I keep getting the same error.

I get error no. 1601, which states that there is a duplicate name key called 'title'. It then asks me to carry on if I don't see the problem as a serious one. If I continue I get the "There is a slight error with the database .....blah ...blah...blah" message and I get the following email:


Database error in vBulletin Installer: Invalid SQL: INSERT INTO forum VALUES (1, 0, 'Main Category', 'Main Category Description', '1', '1', '0', '0', '', '0', '0', '0', '0', '', '', '0', '0', '0', '0', '0', '0', '0', '-1', '1,-1', '0', '1', '0')
mysql error: Duplicate entry '1' for key 1
mysql error number: 1062

I've tried making a dummy database then uploading the changed config to point it to my old database but get the error above all the time.


Please could someone tell me what's wrong?


Thankyou

BTW - i've no telnet but the host as
