CS5 The selected file cannot be linked because its type (audio) does not match the original file's t

Greetings,

I have been working on a very large project using CS5 on my desktop computer. Now I am on the road and bought a laptop so that I can continue to work. I placed all of my assets on a back-up external 2tb drive (which I was able to open without incident on my desktop). I installed CS5 on my new laptop and now when I try to open the project I get the following message "Theselectedfilecannotbelinkedbecauseitstype (audio) does not match the original file's type (audio and video)". This message appears before I indicate the path to any of the assets. Then, when I do indicate the path to each asset, I get the same message for individual files.

Any advice is appreciated.

Thanks,

Jeremy
