I have just received my IV 10 software. It came with Vault 4, but I have only installed IV 10 so far. Using IV 10 I tried to pull up a project from Vault 3 that I had been working on in IV9 and it reads "single user project". I am not able to switch it back to a vault project as it was created in IV9. Do I need to install Vault 4 before I can pull a Vault project up in IV10? If not, how do I get IV10 to see the Vault?
