Hello Sonjas68

I had a similar problem and it was because I was entering the user name wrongly. If you cut and paste user name and licence exactly as shown in the above link all should be well. Re Pegasus and Hexagon. Hexagon is free, and powerful. But Pegasus, at least in my experience, does offer something a little bit different. I've had success with both... and some frustrations with both, however the frustrations are entirely due to inexperience which can only be cured with time, patience and practice.
