The files in question were produced with Photoshop a while ago on the old system. I tried re-rendering the into sequence which I have the photoshop file for, but the resulting file is imported as an audio track only (which is empty as is expected).
I have no idea what is wrong, these files used to work as I've rendered uptowards hundreds of videos with them, but I don't know if something has changed in windows/PowerDirector, or if something is missing in the new system (codec or similar) that prevents it from working. The files plays as they should in Windows Media Player as well as in VLC as they should.
I'd appreciate any suggestions for things to try to resolve this as soon as possible so I can resume video production!

If you require additional information from my system ask and I will provide!
