* i don't use IE its not even worth the HDD space *g*
downloadmanagers like flashget or getright corrupted about 85% of all archives with 1GB+ filesize I tried (only about 200 tries total - could be bad luck or a week internet connection...don't know)
I download (or upload) 2-5 files of similar size (2GB) every week so I had to find the best way
for me to do it
*I do CRC and/or MD5 checks for almost every file bigger than 1 CD
*tried winrar (two weeks old), winace (not sure how old) and ALZip (about 1 month old) - after I got the installer without dlmanager I used winrar and it worked fine
*yes, I did forget dual layer

- maybe because my drive does not support it
Oh, and I didn't try the fileplanet download because I was lucky to get it from NCSofts FTP just before they actualy changed to C4.

But I tried to get it for a friend two weeks ago - sent him a DVD by mail in the end.
The problem with downloadmanagers could be my computer but I hear similar complaints in chats or from my friends.
I will try DAP next time. Never used it before.
