Just a note for those who dislike having to redownload the entire game -- creating an auto-patching system isn't a trivial thing (a friend of mine once spent two months on it), and especially for an independent developer that's a lot of time. Considering how fast download speeds are nowadays, re-downloading 200mb takes like 5 minutes on broadband, which is a lot better than like two months of work for an auto-patcher. Those things make sense when you have millions of people downloading it, because all the 5 minutes in sum are greater than the time it'd take to code an auto-patching system, but for indie games they can be excessive.
As for Plimus not responding, I personally wouldn't trust customer support to those e-commerce service providers (I use BMT-Micro, but they're largely the same). Personally I think handling responses manually is probably a better idea, especially because they tend not to reply if the information is incomplete (which can annoy people who can't figure out what they need to send and don't know what they did wrong), although you have to handle more requests than I did so it's a bigger problem (I only had to handle about 200-300 when I released v1.1 of my game).
