By Just upgraded to MT 3.2 and what a pain in the neck it was to do.
Originally started to upload the files on Saturday but the server hung and I couldn't get back onto it; although other people were still using it fine. After a load of hair pulling I managed to get access again by changing DNS Servers; only for it to fall over again. Changing DNS servers back enabled access again. By uploading the files one by one I got it up only for it to refuse to run through CuteFTP refusing to change File Attributes. A quick trip to FlashFXP and the relative attributes were successfully changed.
Away we went and the upgrade completed. Only for it to continually request a login. Deletion of one file later and all is good.
Heh, not as bad as going to MT4
