What can I say: it is not unpatchable, it is not error filled, and if you can't appreciate getting 10GB of content for free, there is not much I can say except get a decent Internet connection that can download it.
Internet connections that cannot handle large files, because they are slow or proxied or firewalled or have incompetent antivirus programs or have file size caps or have bandwidth caps, are not the fault of the developers.
Everybody who provides assistance on these forums, both moderators and ordinary members, is a volunteer. They do so out of love for the game and not out of an obligation to be servile to loudmouths. They will return help for requests posed decently and in order. The more polite ones will return silence for cursing; the less polite ones will call you out for it.
If you want assistance, after that kind of flaming, you would do well to make a showing of wanting assistance, by calming down, posting details of the problems you are having, what your computer and Internet setups are, and what you have already done to try to solve the problem before you resorted to posting abuse on the forums.
