This worked, but seems a little ill-designed...
Hello.
Could you please search your harddrives for a file called 'Paul.dll'. Please
also try to rename the Paul.dll (if one is found) into Paul.old.
After the file is renamed, please try to launch your application again and let
us know your results.
Best regards,
SecuROM Support Team
I found the dll in my installation of Rail Simulator, and I suspect that as long as I have that file renamed I will not be able to run Rail Simulator.
