Most songs work, new songs don't. Mic echo with new songs

[DownloadFailed]

I did read up on the one topic about a similar mic echo problem, but mine is slightly different. Because my songs work, and HLDJ shows up when it's activated and everything, but 5 or 6 of my new songs that I put into the Audio directory won't play and it just plays the sounds coming through my microphone. I have 145 sounds/songs. Does this mean that HLDJ has a maximum number of songs it can play? Or is something wrong? I tried re-converting the new songs and reinstalling HLDJ but nothing fixed them. Any ideas?

If all the other songs play fine, the new songs have likely been converted incorrectly.
Try the sample wav from the sticky and see the manual page: http://hldj.org/manual/tips_tricks.html#hlaudioformat

Sure enough, the sample worked fine. I tried using a different program called Switch Sound File Converter. I used dBPower Amp before and it worked wonders but stopped for some reason... I guess I'll try using that again and see if it works.
