If i recall this correctly the issue is caused by using the Express version of the MSSQL Server cause this can't comprehend all of the table structures correctly. Therefor i would advise you to change this to a "full fledged" version like Enterprise. Then restore the database backups once again and it should work.

i think can use express version because in tutorials, we use sql serer 2008 r2, it's express version and it's work. I used mssql 2012.
i'm using express version x86/x64 and work fine
Spoiler:
No, this is caused by xp_md5.dll
If you still need help/suggestion get one from me
