One last thing when I right click on the .exe file and then click on properites then click on the Version tab it says that the version is 2.5.0.0
And yes I run the patch.
Aha. Completely disable that evil trash known as Norton Anti-Virus while installing and patching OP and you should be fine.
EDIT: oh but wait... the patch does not update the version info on the executable, what matters is what shows at the bottom of the splash screen.
Nevertheless, if Norton was running when you installed and patched, then try again without that trojan running.
The registry key I'm talking about is:
HKEY_LOCAL_MACHINE\SOFTWARE\Taldren\Starfleet Command Orion Pirates
which contains a string named "Directory" which should contain the path to the copy of OP that you are running (do not modify this entry)
