New to Sonar, having problems

hey everyone,
im new to sonar, got sonar 7 producer edition. ive looked everywhere and haven't found my answer, so please go easy on me. ;) after i have recorded my song, i go and export it as a wave file, which it does and everything is cool, except when i play it through WMP or a cd player, the timing of the song is a little slower, and the pitch is lower as well. it will playback within sonar just fine, it only happens when its a wav. any suggestions? thanks for the help

recorded at 24-bit, 44.1, and i've tried multiple bit rates for the wav file. i dont remember honestly but ill try that when i get home today. there are 2 different wav file options in the pull down menu too, and one asks for additional encoding, like 32bit float point, or something like that.
