Z3100 Print Preview Freezing

In Brief I can print without preview but if I use preview the window appears then freezes- no image to confirm and no button usage. It takes two reboots to fully delete the job from the queue. Very frustrating.. I am using Win 64- 4GBram and Lightroom2.2- latest driver and firmware - So far i have tried reinstalling driver to no avail then in desperation a total system restore to a month prior to the problem manifesting- having updated driver it worked okay for a while then the problem reoccurred seemingly after trying to print 3 x 100mb files next to each other as 8x10's--- Any advice would be appreciated--- Thank you in advance.
