Upgrade issue from 4.1.12 to 4.2.3

[nambisolo]

Thanks for your replies. Sorry if my post wasn't clear but I carried out the advice as instructed by support (rightly or wrongly).

Evidently the query is missing the packageid value but why? The first query in step 14 of the upgrade queries the package table to return the packageid for the insert but the package table is empty. What should it contain?

I could probably add an entry to the package table. It contains the following fields:

packageid - int(10) auto increment
productid - varchar(25) which should obviously be 'vbulletin'
class - varbinary(50) ????

Any ideas what class should be? Or why the upgrade is failing?

Cheers.

Mike
