Hi Mario,
You don't mention what version and patch of SBO you are running. SBO only supports SQL 2012 from SBO 8.82 patch 11 or SBO 9.0. If you are running an older version then you'll need to upgrade before you can use SQL 2012.
Assuming that you are already running on a valid patch, one possible cause is that the SM_OBS_DLL temp folder still contains an older version of the DI API temp files which is why you are getting the error message. Try deleting the SM_OBS_DLL folder in your Windows profile's temp directory and then restarting the DI API connection.
Kind Regards,
Owen
