Could you also try something else.go to my computer, open your c drive> then go to documents and settings>open the folder with the name of your comp, (owner or whatever)>then look for local settings folder and open that.>
you should see a temp folder open that also.> now you should see a folder called vsd_tmpdir open that. select all and delete. the files will go to your trash bin but do not empty it. after your done. try and open vsd. please let me know. if it makes no difference then restore all from the trash bin.
to find out the location of where your files came from originally ( Colosimo) you could always go to the db file vsd makes. it should say there. As far as images made with the shapes tool, you can go into your files folder where vsd holds the images and look for the images that start with IMG and save them as what you want to name them for future use.
Have you made a support ticket?
