Frustrating

I've been neglecting my photography as I work with the new printer. I really do not get on at all well with the CAD software I've been trying (TinkerCAD, Fusion 360, FreeCAD), so my latest attempt was to be with TurboCAD, but I could not even get that to install. I've had this message every time I have tried to install it, and on more than one PC. Their support tried to help, but so far I still haven't managed to get the trial version to run. I'll keep trying though!

Editing this photo is a painful experience - I keep thinking it is a live message from the computer!!
