Help Upgraded to 2.2 - now marketplace app doesnt work - help!!!

[SlepperyEel]

Hi,

Recently uploaded to 2.2 on my Desire. All seems ok except for my marketplace app no long works or connects. I get the following error: "An error has occured please try again later"

Ive had this error since the update over 2 weeks ago. Does anyone know how to fix?

Thanks
