Cannot update from svn server

I’m tring Agilian 2.2sp1 under windows xp with a svn server.
I can sucessfully check out projects, but after other people submit a change, I cannot update from svn server. Agilian open a window saying: "Update project cannot get log of URL:"
What’s the problem?

hi hongsn,

May I have your vp.log file? You can find it in %VP-Suite-Install-Dir%\bin

Best regards,
