Can't patch?

[BlakeyBoy575]

I've been trying since I got my new laptop to install Regnum Online... I have a desktop but I never downloaded it on that computer because I was never really interested until now. Anyways, now I've got a computer that should be able to run this game pretty well but everytime I install it/reinstall it, when I run the game and it starts to auto-patch, it gets almost to the point of completion before it stops, crashes, and tell me there was an error:

"There was an error patching the game"

I hit the "OK" prompt, then this pops up:

Execution of command '.\RegnumOnline.exe (blah blah blah) live_eng SELFUPDATE' failed. (error 2: the system cannot find the file specified.)

Can anyone explain this to me or provide some kind of solution? The game patches to different numbers each time for the most part, sometimes making all the way to 1230/1255 kb, other times only into the mid 1100's, but always in that range. Help. Please. :-)
