Server Error

windows xp pro sp1
e-mail, Hotmail
602pcsuite

I have recently encountered a problem when I try to email an attachment made with 602text. After i have typed the document and click on the "send by email button, I get the "Server Error in '/' Application. HTTP 404, check url /secure/start."
If I copy the doc to a seperate folder, I can email it from there as an attachment without a problem.
Can anyone throw any light on this problem, I have even uninstalled and then reinstalled 602pcsuite, but problem is still there.
Will be extremely grateful for any help.
Thanks
Tipan
