Yesterday, my new install of IDEA 9 [MacOS] seemed to be working well. This morning, however, as I opened a project, it told me it needed to update a plugin. After the update, IDEA restarted, began to load the project (progress bar starts then quickly vanishes), then just dumped to the empty grey IDEA screen.
Every project I try to open produces the same results, whether it's an 8.x or 9.x project.
Perhaps more frightening, it will not open Preferences or Settings or anything else. Help!
I'm running Snow Leopard (10.6.2), using Apple's JDK (1.6.0_17 x64).
