1) If you get some kind of error when exiting Primo (but everything else seems to work OK), try decreasing the number of LICENSES in {Primo2}\license\*.LYC to only what you may actually need.
Many extra license files may have been included to cover as many circumstances as possible, and too many for map and other content that does not actually exist can cause an exit fault.
For instance, if you do not live in a region such as Aus\NZ\RU, you will not need any licenses for that area (as shown in the file name).
