Application Manager stopped working - "A task was cancelled"

[Williamhuynh]

Hello,

I've been using Application Manager - Package feed quiet happily but all of a sudden it has stopped working... with error "A task was canceled" via backlog and via Import Wizard.

Import Wizard shows a lengthy message with dll's being loaded so i've omitted them:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

AdminStudioHost.log shows:

Any idea's to where to troubleshoot/look from here would be helpful. Thanks
