HELP Formatted my TomTom and now it isnt working.

I have a TomTom that has been sitting in a box for the last 6 years. Id like to update it as far as it can go and have it in my car.

I formatted the device not knowing i needed certain files. Now when i download maps(which im still not entirely sure which to use) they don't work.

TTCurrentConfig
TTGO.BIF:
Not Found...
TTGO.BAK:
Not Found...
TTGO.ORI:
Not Found...

Am i screwed or is there a way to get these files back?
