Flash is Being Funny

Recently i have problems with my .fla flash files, it cant be open!my last 2 weeks of works are gone to dusts!Well the swf files still working, but its a mock up, sure i need to do some refining and changes to that, tried some flash decompiler software, but didnt work really well cause it wipe off my library files,

Well all i can say thanks flash for crashing my files
