Cubase cant locate audio files....

I had a crash last week. Since then every project tells me it cant find audio files from “project a”. Doesnt matter what project i open it says this…

sadly in fact 90% of all files form “project A” are missing. when i open it the images are there but they are all blank and no audio files to be found anywhere. I tried every disk recovery tool i could find. these files no longer exist. RAID 1 even and they literally have just disappeared. I have resolved that the entire project is gone and i will need to redo it. When the crash occurred it apparently annihilated files from this project even though i was working in another one. The from fro “project b” are in “project a” and “project a” has ceased to exist.

Any ideas how to make ALL my other projects stop asking for files from “project a”. NONE of them use project A.

Cubase 6.0.3. win7 x64

Open the pool - “remove missing files” - save
