During video production using Camtasia Studio 7.1.2 I noticed that RAM would not hold video production. Using Windows task master in performance tab I ex out of various programs that i though might be holding up the project. Being a large project I left the program to render. Computer was not powered down during this process. I found the project successfully rendered the next day. However after saving project [two files] as camtasia.pro file extension (original artwork) including the rendered MP4 file none of these files were seen in saved locations. Is this a glitch caused by corrupt file production? I have tried using folder options to view hidden files and regit with no success. The project took me many days to produce and now I have nothing to show for it. I would appreciate some tech advice from a white head thanks.
