This problem has something to do with the date. I can open a project file dated on or before Dec 31st 2012, but it will not open anything saved in 2013!
And Pinnacle (Corel) offers ABSOLUTELY NO TECHNICAL ASSISTANCE UNLESS YOU PAY $19.95 PER CALL! What a colossal ripoff!
I will attempt to change file date stamps to verify this....
I am desperate because I have three weeks of editing saved in these project files! I hope someone can make a permanent solution!
