ICA Problem

Hi.

I access a secure web page and run a published application. The app runs by downloading and launching an ICA client. However, I'm getting an error which reads:

Error Number 2314
The ICA Client received a corrupt ICA file. ICA File section named IMS contains duplicate keys named (TWIMode).

I thought this may have been a problem with the app on the website, but I know other people who are running it fine.

I can run it fine if I save the ICA file and edit a line out of it, but when I run it the icon disappears.

Can someone shed some light on the source of the problem?
