[Forum] Problem with upgrade 3.8.x to 4.0

[Numbus]

Alright, this is a stupid problem, I did try to look in the sticky posts for a similar error, if there was I must have missed it and I apologies for this in advance.

The importing went alright, untill step 11 of the upgrade_400a1.php file. It actually did complete everything except this part (see below). Now I realize that it only got to filedataid 163809 instead of finishing. And before someone says it, yes I have been patient and been waiting, but my firefox decided to crash (even though I was not surfing anything else) and after restoring the session. It showed the other steps as completed but displayed a Database Error (as below) for last thing.

I did make a SQL Back up, however. I got 1.5M attachments on my forum and it took me already a good 12 hours to process all these attachments through the upgrade script. Seeing this forum has to stay online for me to make any sort of money for hosting back. I was wondering or it would be possible to fix this problem with a sql query or something along these lines to continue on with the upgrade process that it was trying to complete. So I can on to step 12?

I hope someone has an idea, I thank you in advance for your time.
