For sure, it sounds like Unifab.
Let it try all night and see in the morning. If not, close and reboot the computer and try again.
Uninstalling I don't feel is the answer unless last resort as it would have to do it all over again, downloading crap.
I find I use it less and less, as I don't really use it a lot as it is, and each time then it needs to update models.
They need to come up with a better way to update the models!!
