One of my hobbies is to create audio CD compilations of music. I've been using the old Microsoft Publisher files for years, and have been using the templates to design my own CD covers. I have a few hundred covers saved and also create new covers from the old templates. Yesterday as I was about to print one of the saved covers and all of a sudden, every publisher file in my CD covers folder changed from publisher to Acrobat pdf files. I don't recall doing anything to make this happen. I tried to open the said cover, and my computer would not do it, saying that there was a problem with the file. Nothing I tried worked to try to restore the files back to publisher, including deleting Acrobat Reader from my computer. Then I thought of using system recovery to see if I could retrieve the files. So I went to recovery in settings and when I clicked on recovery to reset the computer, the part that says go back to an earlier build would not let me click on to the get started button and there was a message that said this option is no longer available because you PC was upgraded more that 10 days ago. What the hell? I've done this in the past with no problem, and fixed other issues to go back to an earlier build before. I suspected a possible virus or malware and ran several ant-virus programs that I have, and the programs couldn't find any detections. Is there any way that anyone knows how to get the old files back? When I open my CD covers folder, every cover file is still there and looks like a blank file. I don't want to start from scratch again with a new downloaded CD template because many times I will want to print a saved CD cover to make for friends, etc.. Any ideas to fix this issue would be greatly appreciated. Thanks!
