So, I can't restore any of my old files with using the versioning feature of Lion. Every time I try, I get the following errors. I have the versions available on the right when I'm browsing them, but I can't restore them. The problem happened in Preview and Keynote. Restarting the computer didn't help. Anyone know how to deal with this? I actually rely on the versions in Lion, I really don't have to have to throw them all out and start again. ---------- Apparently, while in the Versions interface with a preview document, I can export the document as a new PDF to my desktop. So clearly the old versions of the file still exist and can be accessed (at least for preview). Weird. Any thoughts on this?
