corrupt excel ftp download

[rcdc]

* FlashFXP v3.0 build 1015 registered
* OS Win2K
* Running behind microsoft ICS
* Running firewall Norton personal firewall
* Running Antivirus AVG 6.0
* Network ICS with satellite broadband download (though flash fxp just uses the dialup connection only as far as I can tell)

when I try to download a commission junction MS excel spreadsheet from datafeed.cj.com the download is always corrupt regardless of whether I choose binary ascii or automatic download. To confirm it was flash fxp I installed a trial version of cute ftp which downloaded the same file perfectly every time. However I much prefer flash fxp to any other ftp program I have tried. I would appreciate help as the trial on cute ftp will run out soon and I need this datafeed from commission junction

Many thanks
