I've used polyphone to convert sf2 to sfz in bulks for some time. But now I can't seem to do that anymore... :l
I don't know why. I've been using the win64bit version, then tried the win32 bit version, but both give the same results. Stuck in "Operation in progress" for 20+ minutes and over.

I would bulk 10-20 soundfonts and it seems the only way to get by is to do them one by one. I've reinstalled the program but no avail, same stuff happening.
