Broken Menu Files (Is This A Flash Fix?)

[xkcd42]

If my assumptions are correct the mainmenu.bar file has been corrupted. I can still call, access my alarms, calendar, and texts (thanks to the shortcut keys I set up), but the menu is completely inaccessible.
I assumed that, since flashing is like reformatting a hard drive (thanks for this description smitty), a flash would restore the corrupt file(s) to their original state.
It seems that this means I was right, but any other way to replace the corrupt files should work.

By the wayside,
Sorry for posting this in the wrong section originally.
