I saw there was an upgrade for Windows (2.7.5) and decided to install it. Now, the program sees the saved curve name under "Curve 1," but when I go to open Curve creator, I get "Address violation in address x x x x in module QTRgui.exe. I click OK and the curve creator box opens. Then I try to load the desired curve and get the message, "Error in ink description at Line: 2." Running Win 7 and used the default location during the upgrade. It's been a few months since I last used the program and suspect it may be something simple?
