Hi
I explain briefly what happened:
To create courses on the recommendation of my company, I started using tried and tested CourseLab of functioning.
For problems on the PC I had to uninstall the product, but to attempt to reinstall it when I have to create a new module no longer shows me the list of templates thus preventing me to continue:
data templates are all there,
if I install on another pc all works,
The combo box should show up with the names of the resulting template previews will be empty.

I state that before the new installation I cleaned the registry so the new installation was as if the product had never been installed.

Any idea how to solve the problem??
