Strange, I had a notice in game saying graphics or sound is corrupt and may affect the game. It didnt and I carried on as normal
When closing the game an error report is created and I send it to Blizzard. Its done this about 5 times now in the past week
Not had crash / error problems for ages
I had this problem before, it caused me no end of grief until I figured out what the problem was.
Mid game my game would suddenly slow to single digit fps and tell me something is corrupt. As a temporary solution I'd crank my graphics to lowest and it would resolve the issue. Once I quit the game it wanted to send an error report on a corrupted file within the game and asked me to repair. Half the time I repaired it didn't actually find any problems, sometimes it repaired a file (always a different one each time this happened).
I uninstalled and reinstalled, but it wouldn't actually let me reinstall as it kept having corruption mid install on random files. I downloaded the installer multiple times onto different hard drives and it always had the same issue. Eventually I got it installed by using safe mode.
I ruled out every hard drive, did memtests, swapped sticks and all the rest, could not find a single thing wrong with my hardware. I formatted multiple times and still the issue remained. Every other game worked flawlessly, no corruption in anything else aside from Starcraft 2.
Finally, I decided to up the voltage on my memory as a last ditch solution. I wasn't running it at max voltage, I was running it within the rated limits, just not max.
I set the voltage to max and every single problem with SC2 went away instantly and has never returned.
The moral of the story is that SC2 is a very sensitive game and even the slightest hint at corruption in anything will cause it to go into major states of panic as you have witnessed. If it says there is an issue, there probably is one, even if nothing else on your computer notices it.
So check your HDD's, test your RAM, check your voltages and get rid of that annoying problem
