I have found contacting GDI support with an email or by phone has helped a great deal. My last challenge was the edit problem, couln't edit existing blocks or newly created blocks.
Recent help email from GDI support said they couldn't duplicate my problem. Seems it corrected. They suggest I install an updated adobe flash player, I did and it seems to have made a difference. Here is the link they gave me;

Hope this helps.
