Haha of course.
Thank you, it took a very long time replicating and enhancing the original maps from MQ. Yes, theres some backtracking later on in the game hence why some chests you cant get to yet.
It is safe to download the new version and restore your game from that one, all progress will be kept (put the new version in a new folder to be safe) and bugs that may have cropped up in the old version will be fixed and work for your new version.
Stat boosters are a definate, but after Cormac's ship quest you do have the option of buying really neat gear, so keep that in mind :)
