Metroid17

Should I also try the 1.1 beta?

Well...If you have a large enough flashdrive, you may be able to just download the game then slap the game directory and all the necessary files onto the flashdrive. Even better, you may just get a .exe file to install it, which you can just put onto a flashdrive, take it off on the non-internet computer and then install. Not sure how viable this is.
