Thanks boRg.
I have just successfully upgraded by importing all new tables into my Access DB, comparing them with the old DB and adding new filelds into tables as required. New Tables were imported by default.
All imported tables are named 1whateverTable as they are duplicated, these I have deleted after comparison.
Then only 2 things to do to the DB:
1. Enter 0 into MovedID in tblTopic (all rows)
2. Enter 5 into Upload_avatar_size in tblConfiguration
All old ASP files were overwritten and all is fine.
Hope that helps someone else. I tried the changed log first but to no avail... This way is easier and should be less suseptable to errors. I expect there may be a few other mandatory fileds that may cause issues but the forum seems pretty stable.
