I have Windows 10 and am using Power Tracks Pro Audio 2015. I recently re-installed power tracks and when I tried to record a guitar part, I pressed record and when trying to save the recording, got an error message, "Error Converting C:\pt\INPUT.TXT". I also got an error message "File Access Denied (read-only file, or in use by another program". I tried deleting ptw.ini, but to no avail.
