MP3 Playback is slowed down

[tamora]

Win XP
Replay Music 3.7
Source is Spotify

I record a track and save it and when I replay it, the whole track is played very slowly. I have tried to playback using iTunes and Windows media player but they all give the same result.

How can I stop this?

Tried a system restart - No change
closed all programs - No change
Tried it again this morning with a different album (P!nk instead of MGMT) and it worked. Now just testing MGMT again, and it also works.

Not sure what caused it, but it's fixed now so I'm very happy.
