I have upgraded to the latest version of Lightroom and it seems to work fine except for one thing. When I go to 'edit/preferences' I get an error message something like 'LoadLibrary failed with error 1114: A dynamic link library (DLL) initialization routine failed'. When I click okay in the error message box LR crashes and shuts down. It will start right up again and seem to work okay unless I try to access the preferences again and it does the same thing. Don't know what is wrong but it needs to be fixed.
