Try opening in safe mode by holding the SHIFT key while opening the project. This will give you the opportunity to skip plug-ins while loading.
It's opening fine...and it closed done okay...but my question was in relation to Plt then freezing before I could open another project...can't hold down shift at this point.
Also, when I had X1,X2 on the sytem, X3 would open very slowly. When I un-installed X1 and 2, X3 sped up it's opening. However, I'm finding Plt is very slow to open.
