DEMO TECHINCIAL HELP!!

[america person]

ok, i wanted to dl the DW demo, and so i go the link on subsim, start dl the demo, and here is the funny business, i start the dl, everything is fine...but then i hit a button, NO CLUE wich one either, and the dl stops, with the empty .exe file sitting on my harddrive, it is not the install wizard, just this Dangerous_waters_demo.exe, that TAKES UP 0 bytes....none nada, zip. and so when i try to delete it, it says that DAngerous_waters_demo is being used by another person or program....WHAT THE FECK IS GOIN ON? i tried deleteing, dragging and dropping it to the recycle bin, and i give up. on a further note i dl the demo again successfully last night as i slept, ran the install today after school and it is a kick ass demo, suberb....but i jsut want this .exe off my pc, before it messes up my pc. it currently appears harmful, but im not sure, don't want to take chances. If any of you guys know how i may solve this problem my AIM is oidkmfan, MSN is tla@qpcteam.com and my icq is 204906912. i also have skype, and that is t-money_treamhis.

thnx for the help...TRAV
