It's not that hard. Just install the english trial and switch the files over, badda bing. Would be nice if they had a language installer in the installation though.
Yes, but imagine that they change that system (it wouldn't surprise me) and people who purchased the new english version need to enter their english serial to get access to further english updates...
Personally, I find this really unfair, at least for those who ALREADY BOUGHT a CSP LICENSE.
Imagine that you have a PC and your operating system is Windows but you decide to get a new Mac computer. If after buying the CSP license you are able to download for free the Mac version as well, is it too difficult to provide their customers the english files as well if they want to?...
Mac users who get a PC with Windows and viceversa can download for free a version for their operating system, why someone who already bought the program license and doesn't speak japanese can't do the same but with an english update? THE PROGRAM IS THE SAME, from the same company, distributed by the same company and has the same features and updates! This is to me as retarded as paying a new EX license to download the Mac version for an hypothetical new Mac computer.
