[Wine] Visio doesn't start anymore

[Subbeh]

I've been using Visio 2007 without any problems until today.
When I start it using the applications menu, its starting up for a good 10 seconds and then just stops (I don't get a GUI). When I start it from the terminal, it immediately give the following errors:

~/.wine/drive_c/Program Files/Microsoft Office/Office12$ wine VISIO.EXE 
fixme:actctx:parse_depend_manifests Could not find dependent assembly L"Microsoft.VC80.CRT" (8.0.50608.0)

err:module:LdrInitializeThunk Main exe initialization for L"C:\\Program Files\\Microsoft Office\\Office12\\VISIO.EXE" failed, status c0000135

How can this have stopped working all of a sudden?
