If you just own 1st copy of CoH and want to play Online, you will get an error message(download failed try again later). You have to download Patches from http://cohpatch.relic.com/
You must download patch 100-140 then 140-2101, 2101-2201, 2201-2202 ex...
13 patches total. last patch is 2601-2602.
This can get confusing, because later patches appear under the expasion games. There is no need to own them. Just download and install to the latest patch.
I hope this helps somebody.
CoH 2 will be out soon thats why im here. Need to get my skills back so that im ready. PEACE!
