UPDATE:
I've downloaded a 3MB patch more than 3 times, but not each time I boot up RE: ORC. So, I mailed Capcom Europe to inquire about the patch, and see if I can snatch some patch details while at it.
Unfortunately, they claimed they only know of one patch, and I asked if it's possible for the servers/game to be stuck and prompt us to download the same patch every time. No answer on that. I also asked for the patch notes, or at least some details, but they claimed they have none.
Extreme lack of organization, obviously. I asked them if they could pass them on so I could share with the RE community, but they said they couldn't do anything about it. Sadly, the mail I wrote to Slant Six last month has probably landed into a digital trash can already. Shameful and disappointing...
