I'm also having the same problem. I found this text in the FeelThere/ERJ folder.
"driver={Microsoft Access Driver (*.mlb)};dbq=C:\FS9\FeelThere\ND\nd.mdb
Trying Connect
Connect error
Microsoft OLE DB Provider for ODBC Drivers : [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Requested operation requires an OLE DB Session object, which is not supported by the current provider."
I am using windows 7.
I have reinstalled FS9 and the ERJ multiple times but still no good.
The nd file is in the folder.
I'm anxious to hear if anybody has a fix. I've been simming since '95 and have never had problems before. Had the ERJ when it first came out.
Hate windows 7.
Kostas,
I was wondering if you have any other planes with FMC or FMS that work. I've been only flying my planes that don't rely on them.
Thanks for any help.
