installing patches

hello, i just download eastern front , and i cannot access the sovient army. i have been readign through several forums and it appears i need to download a patch as well. am having trouble downloading a patch, because i have no idea where to get it from and i also dont know where to specifically install the patch. my current version of coh is 5.1 i think.

just a correction to my above post,  my current version is 2.501, and i have managed to get the patches. when i try to install them they give me an error 10242,  " a complete, valid coh could not be located"
i installed my game in the local C: ? how do i solve  this?

Most likely your intallation is either pirated or corrupt. If it's corrupt try reinstalling CoH from your disc/steam and reapply the patches. If it's a pirated .zip version to unpack & play Eastern Front mod won't work unfortunately.

Am i allowed to support people whom have pirated copy? Since i know how, i had been one so...

If you want to do it, it is up to you, but if I'd recommend to talk with him by PM.
