Changing Tempo without moving regions

[studio de' Lara]

Hello,
I have a song that was done in Logic at a tempo of 65bpm.
I rendered the tracks in Logic and imported to Tracktion for my final recording work.
I screwed up and didn't set the tempo in Tracktion to 65bpm, I left it at 120bpm.
I need to change the tune to 65bpm so I can have ACID in Rewire mode at the proper tempo to add supplemental loops / effects.
How do I do this without having all the regions get screwed up / move with the tempo(everything is nice and cut up)?
Regards,
Rich
