WinSCP problem connecting to Cisco ASA 5505

I use the latest version of WinSCP v4.0.6 and try to connect to ASA 5505 or 1800 router. I authenticate successfully but the session does not connect "our shell is probably incompatible with the application"

What do I need to do?

I have Secure Copy enabled on both devices and SSH is configured and working properly.

Thanks!

Have you read requirements? Would it help?

alright. so is there a good alternative out there? other than pscp (looking for a gui)
