Dreamweaver Quits on Launch

Hi,

Have been happily using Dreamweaver CS6 for quite sometime but after a recent restart the app no long launches. Quickly into launch I see this error in the crash report:

*** Terminating app due to uncaught exception 'NSImageCacheException', reason: 'Cannot lock focus on image <NSImage 0x18d8e570 Size={0, 0} Reps=(
"NSCachedImageRep 0x18d8f230 Size={37, 0} ColorSpace=NSCalibratedRGBColorSpace BPS=8 Pixels=37x0 Alpha=YES"
)>, because it is size zero.'

Any help would be appreciared...thanks!

Rick

p.s. All other CS6 apps are opening and closing just fine.
