Thanks, Peter. I thought too it might be content since the file was started off in V5 prior to the update. However, since receiving your reply, I put a few images & effects directly into a new (V6.5)file. Unfortunately, the same thing happened:I click to Create Video; Video builder opens; pte files are visible but without detail. If I click Next to create Title page, computer reports Video Builder (not responding).The program just hangs and I have to do ctrl/ Alt/ del to close. Just don't get it! Can't understand why uninstalling doesn't fix the problem. Will try Version 7 as suggested by Administrator's response. Thanks again. janet
