the upgrade prosess was:

1. copy paste the upgrade package

run the upgrade proses and evertything is "success"

but when i click button "click here to access your portal" there was an error come up.

do you guys have any idea what step that i missed?

thanks in advance

check you have .net3.5sp1 installed (the requirements changed around that version) - also, as this is a PE issue please raise it via the professional support network, they will be happy to help with the problem.
