A box pops up with a couple of options, like 'Close Window' and another one, can't remember. There was no way to open the program. I read somewhere to reinstall PD11 as Wave Editor was 'inside' it. After trying everything I could think of I uninstalled PD11, big mistake. I had all the hassle again of trying to find a download without any luck. I eventually got a reply from Cyberlink that gave me links to downloads, but only for a couple of days!!!! Why? I really don't understand this time limited download crap. I quite like PD11 but if I ever have to replace it it won't be with a Cyberlink product. Thanks for taking the time to help out stevek, It's all working again now.
