AMP3.cc 100% Converting bug?

I wanted to download a playlist instead of manually going one-by-one down the track list. AMP3 shows that the playlist (which is way under the 4hrs limit) is 100% converted but it's not doing anything else now. Its been saying 100% converted for 15 min+ now. This has happened before with just a single song too. Is there a way to fix this or is this an actual bug? Thanks!
