I'm having similar problems as tmccarthy had back in 2006: "Can't print flipbook." I loaded the software, loaded a video, told the program to do 50 images and hit print. It printed fine. Forgot to put crop marks in, checked that box and printed it again. No problems. Came back a couple of days later with a new video, checked 40 images, no crop marks as I have the pre-cut biz cards. No printing. Hangs up in the printer cue. It says it was sent, but it doesn't print. Opened a MS Word document and printed from there, no problem. Shut down the Flipbook software, opened it back up. No printing. Re started the computer. No printing. Tried the test page, nope, tried the original video that worked before, no luck, etc. please help. It worked great the first time and I'm all set to do more with what appears to be the only tool out there to do this. Thanks for making it.
