I use the Free Lite0C version of the a7 game engine. I did as you suggested in you last post, but that did not fix anything. I guess it is possible that the installation was corrupted, however, it runs the workshops fine.
I can only open the samples to the workshops, not the actual tutorials themselves. When I try, it says "there is a problem with your internet connection", but my internet connection is working. I wondering if the 2 problems are related. I downloaded both in the "Download" section of this site.
