Anytime I try to download any tab-delimited files or save them to the temp dir, I'm always sent back to the login screen. This was brought up several times before, but it was never answered. Any help?

But when I click Download Complete tab-delimited .txt file to edit link, it ask for admin login, I login, click the link, but it still ask for admin login, then when I click the link or other link it always ask for admin login
FYI, I'm using EP Version 1.2.5.4 on Zencart 1.3.9h

Thanks!
