I can't log into the game

[Xero_Aurion]

So this is the situation. After downloading the game I install it and everything seems fine. I open the game get as far as typing my username and password. Then afterwards a third screen appears (I'd assume the game is loading up at this point) and as it's almost loading it closes and I get an error message. This is what it said:

NOTE: this error had my username and password in it so I replaced those terms with <username> and <password>

This is the message:

11:50:44 PM: Execution of command '.\RegnumOnline.exe <username> <password> live_swe SELFUPDATE' failed (error 2: the system cannot find the file specified.)

I decided to check the details and this is what I got

11:50:43 PM: can't open file 'SelfUpdate/RegnumOnline.exe' (error 5: access is denied.)

11:50:44 PM: Failed to copy the file 'RegnumOnline.exe' to 'SelfUpdate\RegnumOnline.exe' (error 5: access is denied.)

11:50:44 PM: Failed to copy the file 'msvcp80.dll' to 'SelfUpdate\msvcp80.dll' (error 5: access is denied.)

11:50:44 PM: Failed to copy the file 'msvcr80.dll' to 'SelfUpdate\msvcr80.dll' (error 5: access is denied.)

11:50:44 PM: Failed to copy the file 'msvcm80.dll' to 'SelfUpdate\msvcm80.dll' (error 5: access is denied.)

Does anyone have an idea as to what happened? Do I have to adjust my firewall or something because I'm all confused now and I just want to play...
