Despite double and triple checking (and uploading) both upgrade and full versions of 3.2, I am continually getting the error message as follows:

Can't locate object method "set_instance" via package "MT" at lib/MT/Bootstrap.pm line 43.

I don't know where the breakdown is, but in order to log on to MT I have to restore my backup.

What gives?

I've got the same problem...
Anyone has a solution?

check out this thread. Still no answer but its getting some traffic.

I'm surprised this hasn't been discovered unless my search skills are sub-par.
