I have q'nique 21 with QCT Beginnings. It works very well for me, but there is a learning curve...
A couple of questions for you:
Does your computer meet the minimum requirements for running QCT? If not, that could be at least part of the problem.
Do you have the computer set on Airplane Mode ON? That turns off the internet. QCT gets 'interrupted' by WIFI sending or receiving 'stuff', so it will seem y at QCT is not working.
Are your Windows updates current? I'm not sure why, but Windows updates need to be current or the QCT software doesn't function right.
Run a Windows virus scan before you start QCT. If not, the virus scan runs intermittently (it's not something you can schedule) and interrupts QCT software.
Set your screen time out to: Never. When the screen times out, the next time you try to do something on the screen you will not get a quick response, which can cause problems with your quilting.
I also turn off Virus Protection and Firewall protection, again, to prevent software interruptions of QCT. But they are turned On again before I turn Airplane Mode Off.
If none of the suggestions above help/resolve your issues, Call Grace Company for help. They are excellent and do get back to you fairly quickly. Also, visit Facebook sites "Quilting with Grace" and "Quilters Creative Touch" sites. There are many resources and videos that are very helpful.
Good luck!
