[Poltava]

I have started work on a SCW Republic campaign, and want to use the classic "Ay Carmela" as menu music. The problem is that I only have it in MP3. Have I tried a few conversions programs, but the resulting Wav files has either caused IL-2 to crash, or turned out redicolusly BIG, like a 28Mb Wav for a 600Kb-ish MP3 file.

Any suggestions?
