Hi,
We use premier 5.1, I don't have a corupted database (I just ran the optimiser to check) but we did have to revert to SME version 5 with updates.
I tried to run 5.1.2 for about 7 working days but the system became so slow that MYOB would give either termination code error 1266 or 1234.
It wasnt just MYOB, we had problems with anything that access a data file stored on the server. The really frustrating thing was the problems were random, sometimes it worked sometime it didnt.
All seems fine on SME 5 and we ran for 12 mths on 4.12 without problem.
I'de be very carefull using 5.12 as a production server at the moment, the forums are getting a lot of problem posts regarding 5.12.
