Same problem, immediately upon upgrading from bitcoin-0.8.0rc1-win32 to 0.8.1, on Win7-64.

Chose Cancel. The .sst file referenced did not exist, but no problem creating the .sst file with Cygwin "touch". Deleted the .sst file I had created, restarted Bitcoin-Qt, ran fine the second time, no further mention of .sst files in the debug.log. 2-month old SATA laptop drive with no problems.

Code:

Oh boy, this is one those "geeky" things that the masses won't understand. How did you implement this solution, in layman's terms? This is happening to me as well.
