My Windows Movie Maker was frozen, I have instantly pushed Ctrl+S to save if it can still be saved. All my videos suddenly disappeared in my project leaving the workspace white. I waited for the program to recover in vain, then forced closing. Tried to reopen my file but it was all white. It would still play the empty, white videos though. The program suggested me a file recovery, but the recovered file was an even emptier new project. Opening a the original saved project and the one recovered by WMM in Notepad shows they both still contain a lot of information, so I did not stop hoping. Please help :(
