Playback speed. Sample rate issue?

I recently recorded a voice over session.  During the recording, I played it back to review several times, sounded good/normal.
The next day, I loaded the project to edit it.  All tracks were slightly fast and higher pitched, about 9% higher and faster.  It sounds the same in Sonar X3 Producer (where I recorded it), PremierePro where I plan to edit it with video, and even Window media player and another 3rd party player.  All say 48K/16 bit.  I believe that's how I recorded it, at least that is what my Sonar setting said when I went back to look.  It sounds like it was recorded at 44.1K and playing back at 48K.  Any way to correct this other than time stretching?
