I've been working on a map for three hours or so in one sitting (WIP, not submitted yet) and everything was going fine in the editor ,but I had to close osu for a bit.When I opened up osu again, and tried to work on it again, I kept getting an error message about the Audio not being able to be loaded.So I changed the audio file several times, changed the name, changed the type even. I even put in a completely different .mp3 file in the folder (with the .osz files and .osb file intact) but it still gave this message, so I guess it's not a problem with the audio file. I deleted the diffs, the osb file, even the bg but it still gives this message 
I even tried remapping the song, it still gives this message every time. Please help.
