Just upgraded to the new 11.2 version and it seems to run ok. A few problems with some character pmd files not mapped correctly and face morphs not working. But once i re-mapped the files and re saved it all went ok. No problems with serial numbers or anything else really. Unfortunately on the upgrade i installed the new Bondware version back in the old Smith Micro directory. It all works so far, so i will leave it where it is for the time being. Best let sleeping dogs lay eh..

Thanks to all who gave answers.
