Trying to get back into sh4!

[Aviv]

Okay so a couple of monthes back i decieded to take a little break from SH4, and I uninstalled it. But now i'm settled into my new home for a couple of weeks I want to get back into sinking ships and sailing around until sunrise. But tonight I tried to install it again, but it won't! I get as far as "The Installsheid wizard is installing Silent Hunter 4 Wolves of the Pacific" but nothing happens. Before you get a neat background and the blue bar fills but this time I get nothing. Just the blue bar stays where he is! Tonight I'll have to install another game to play, which is a shame cause i chose SH4. I guess it just doesn't want to be played
