Map won't show in DB2!!!

Guys I'm having a HUGE problem. Last night I was working on my map and saved, all seemed normal but this morning when I load the map when it asks for a map for loading NOTHING shows. Please help me, this is my first map and I am very proud of it, I don't want to revert to an earlier copy! The backup files don't show anything either but I am dragging and copying them on the DB2 exe. Is that how it's done? PLEASE help me, I don't want to lose significant progress. The map won't start in Doom either, the normal E1M7 starts. OMFG!!!

Nevermind, I fixed it. I can't wait to finish it and show it to you.
