A few months ago I upgraded to VS2010 - at the same time I thought it would be good to upgrade to SQL Express 2008 R2.
It turned out that there was some compatibility issues between the two - "...cannot be opened because it is version 661. This server supports version 655 and earlier. A downgrade path is not supported." After much trouble I restored the database and have done most of the stuff I need through VS itself.
Now I need to use SQL itself and am positively scared to death of what it could do to my database again. Can anyone offer any advice - it is a service pack update or something...?
