MP3 export doesn't work
When trying to export as MP3, MuseScore asks for the location of lame_emc.dll. Drilling down to that and pointing to such a DLL (lame3.99.5) results in an error:
Error opening lame library
Could not open MP3 encoding library!
Hitting the OK button (which is the only choice) leads to a crash (hence critical).
Same thing happens with any lame_enc.dll I find on my system (there are a few, scatterered all over the place)
Tested with GIT commit: 6c1d0d2on Windows XPpro SP3
