Ohhhhhh, we're on the same wavelength then
If anyone has the guts to use regedit, you can find the nolimits data at:
HKEY_USERS\S-1-5-21-1645522239-152049171-1343024091-500\Software\NoLimits Coasters\NoLimits Simulator
The ID in there may be different, but there's only two on my system and I'm guessing not many more on yours - just give them a try
If you want to export JUST the nolimits data, navigate through your registry until you find the "NoLimits Simulator" key, click on it, then hit Registry > Export Registry File. Save it somewhere safe, and you're set.
The advantage of doing it this way is that your graphics settings are also saved
