Not sure who I should forward this information to but I found a bug with the site. I purchased Version 11 on Friday and when I attempted to download it from the site I am brought to http://www.pcstitch.com/Download/SwDL.aspx?SID=94. The page says it is version 11 but when you select Windows 10 and hit Start Download you get PCStitch_Inst.exe. When you open this file it says PCStitch 10.
If you go to the same URL but change the D in Download to lowercase (http://www.pcstitch.com/download/SwDL.aspx?SID=94) and follow the same steps, you get PCStitch11_Inst.exe which installs as version 11.
Took me a few hours to figure this out and wanted to make sure nobody else runs into the same headache I had.
