System update 3.0 - Error executing autoconfiguration script

[bluegene]

Recently, I installed system update 3 manually from lenovo.com cuz previous version hang at connecting package index server.

However, sysyem update 3.0 still has the same problem, instead of no response, it shows:

Error executing autoconfiguration script file

My access connection didn't set proxy at all.

Anyone could help me?
