I had the same problem. For me, this issue turned out to be that I was using LAME v3.99, but MM apparently requires LAME v3.98. Once I switched from 3.99 to 3.98, all was well.

Aha! The problem was that I was trying to use the 64 bit version. Once I switched to 32 bit, it worked. In case anyone else runs into this...

I am having this problem, too. I've tried downloading lame_enc.dll from several different sites (sourceforge, rarewares, etc) and always get the same result after moving it to the MM folder. Is it possible there's a compatibility problem with the latest version?

You should be able to replace lame (the free version only has 30 days of MP3 encoding), you may have downloaded a corrupt or incorrect version.

I don't have MediaMonkey Gold. The reason I did this was to convert files to mp3, is that not possible with the LAME dll?

Revert to the older encoder I guess.

Anyone know what to do? I've copied the latest lame_enc.dll version, removing the old one.

When I start the process of converting a file to mp3, the bottom bar shows for a split second and then the above error appears; 'Error lame_enc.dll can't be uploaded'.
