SMFPack Gallery + Upgrade to 2.0.8

[digiflash]

Recently I upgraded to 2.0.8 from 2.0.7.
After installing the SMFPack Gallery and trying to add a category I'm getting a DB error.
The field user_id is missing I should run the upgrade.php but where should I find this file?!
Maybe it's part of SMFPack? I don't think so.

Any issues with paid SMF Packs material should definitely be handled on their website.
