Restoring Movable Type
Uploaded file was backed up from Movable Type but the different schema version (4.0036) from the one in this system (4.0066).

It seems that something from both of MT4.2 and hosting side should be reconfigured. Any idea to fix this problem?
I've seen this problem with backup in other variations as well. I think the backup feature is intended to only be used within the same version of Movable Type (sorry to state the obvious). For future reference, backing up the database is generally the far safer bet. If you're using MySQL, this'll help you avoid this issue:
