Locator data lost after transferring saves between PC's

I have moved all my tracks/peaks/mp3's etc to my laptop from my desktop PC but but all my locators that I spent 2 days setting haven't saved. All the beat grid data/peak data etc has transferred OK.
Is the locator data not saved along with peaks/etc or do I need to do something else ?
Am I going to have to re-do everything again ?
The most annoying thing is I had half of the song with the set locators on my laptop to start with but overwrite them when I imported the newer files from my PC and now the the info is lost.
Is there a way I can roll back to a later date ?
Sorry if I am being dumb but I have searched hard on here but didn't find anything.
