Hi Jinev,
IIRC even though the KB article you found indicates the percent (%)
others have encountered the same issue when using other symbols in the
file name. If you rename the file and remove the exclamation point (!)
and the error goes away then I'd say that is indeed the problem.
In which case the company needs to be willing to do something such as
rename their files since I'd say AutoRecovery is a little more
important. :-)
