As the title suggests, both copies of Version 5 are crashing on application startup.

I get the typical S3D startup screen, then after a second or so, I get the blue 'working' wheel adjacent to mouse pointer and then it crashes and vanishes.

I need this sorting ASAP please as I have things to print!!

Thanks in advance

Already provided a suggestion in your other post, so we can discuss there:
