Teamsite error - webedit pro

System

I just got a new laptop and now Teamsite wont allow me to bring up forms that previously worked. Other members of my staff can bring up the form on their pcs without any problems.

I have removed all previous versions of SUN and installed Sun JRE 1.4.2_06 per the recommendations, but the problem still exists.

See the attached screen shot of the error message that I am getting.
Any idea on how to resolve this problem? Will a re-install of MS-IE work?

Please advise

T.S 6.5, Win XP Pro

Thanks
