On the cusp of 10.0, I think I’d wait too.
You pretty much need to move that project to another computer. If you don’t have another computer, there’s a “hard work” solution, maybe. Go download VirtualBox, install your favorite version of Windows that supports Vegas Pro 9.0 into a virtual machine. Load up the project in the VM.. you have another month, though it’s probably going to be a slow one.
Depending on your project, you can get at much of it loaded into Vegas 8, I believe. Once you’re back in to Vegas 9, try exporting to an AAF file (Save As…, then find the AAF tab). This is a standard NLE interchange file. It doesn’t export plug-ins or plug-in settings, but it does exports your cuts and some other useful information. I don’t recall offhand if Vegas 8 supports AAF, but it probably does.
Note also that AAF export is missing in Vegas 9 Pro 64-bit for some mysterious reason, so you need to do this from the 32-bit version.
