Can someone help please:

ibrickr recognises my phone and goes through the motions of installing even telling me its done but the phone does not restart and when I do it manually nothing has been installed, I can view folders no problem and see installed apps but I cannot change anything by installing or uninstalling. The strange this is When I check the error log it tells me the installed was ok with no errors.

I tried another pc and got the following error

Ex_findphone
S_iBrickr version: 0.91
S_iPhoneInterface
E_Problem registering main callback: -402653180
USBMuxListenerCreate: No error

maybe this will help someone identify the problem, I'm at the end of my tether with it, wanted to install openssh so I could attempt jailbreakme but cant risk that without the means to install openssh and test out winscp

help appreciated
