I tried this one and it didn't work.
First I turn it to English.
Then I click on the no time limit button.
Then in the left hand box I click on C:/, then program files, then Paradox Interactive, then Modern Day Scenario 2.
Then HOI.exe pops up in the right hand box.
I click it, it highlights, and I click patch.
Then an error message says Runtime error 75, Path/File access error.
I have no idea why, if I click that button in the file the game starts, so it works. The game just immediately ends because it's past 1953.
The patch that came with that mod set off the antivirus, and the patch that came with 1914 didn't work either. I'm cursed.
I assume you're using Vista or Windows 7 ? If so your problem is that you installed the game into Program Files. These two operating systems 'protect' files from users, and can make even simple tasks like deleting old save games a hassle.
It's a lot easier if you install games into folders outside of program files eg games\doomsday.
If you don't want to uninstall\reinstall, you could turn UAC off and try to run the NTL again.
