Error E1115: Bad format (24 & 32 bit RLE only)

i keep getting this error for a map .. For some reason i cant make a new map anymore ..

maybe i should explain some more .. Im changing levels.. i built 2 levels that work fine .. Im trying ot make a 3 level but it just wont work .. it keeps saying i have a RLE error in the map .. even though its just the same map as before named something different ..

LOL !never mind .. i spelled a level file .wmp instead of .wmb..

ok i have officially been working at this for too long today
