Thinapp stuck in 'Pending Install' in View Administrator

Hello,

So I've got a ThinApp that I assigned to a desktop in View Administrator, then I un-assigned it for testing.. Now I want to re-assign it but it's status on this VM is 'Pending Install', it's been pending all day now. I've rebooted the VM, made sure that the ThinApp is indeed removed from the VM.

The ThinApp admin guide says for this situation to go to Inventory -> Thinapps, then click the thinapp name, then go to the Desktop tab and click Retry Install, but all 3 of the buttons on that screen are grayed out so I can force removal of the status or reinstall.. So what do I do now??

Thanks!!
