How long is the upgrade process suppose to take? I have started the upgrade process on the X1 about 10minutes ago and it is still stuck on the "Downloafing Tsunami_v62_gui.he_" file. The progress bar has not moved and I am scared to disconnect, hit stop, or anything in fear that it will damage the projector. I am upgrading from ver 4.1 to ver 4.3. Please help!
