Wont let me install ... :/

Wtf is going on? I d/l the 1gig file then go to install and i jus get this. The blue bar occasionally moves as if its still installing but it doesnt do jack. I check the folder i saved it to and theres jus a file there thats 3.99gb big called Data1.cab. After time i jus clicked the X and decided to try again, and again, and again... same thing happened. Then i tried checking the box underneath where you choose wot dir to save to (dunmo wot it is. When i click "??" i get an error saying "Runtime error 204 at 0000549C". I think i figured that "??" just be cancel "?? ??" is for About and "????" is to continue... Please help if ya can..

Installing it takes longer than downloading it, that all I know to tell you.

Actualy it take much longer to download then install took me 6-7 hour download, installing was quite short and patch took 2 hour 30 min~.

And for the error i have no clue you might want to go to http://lineage2.tenstones.net/ see if someone had similar problem.

I only get the error when i click "??" button. Ahh well, thx for your replies. Ill check out that site now.

Edit: Checked that site and there was nothin
