Missing environment access after migration to BPC 10 NW

Hi,

I successfully migrated from 7.5 to 10, followed the procedure from SAP migration note and blog

http://scn.sap.com/community/epm/businessobjects-planning-and-consolidations-for-netweaver/blog/2012/04/05/migrate-from-sap-bpc75-to-sap-bpc10.

Had couple of issues with backup zip file size, resolved them by deleting logs. Had to uncheck 'master data' when restoring.

I used the mapping file which included the header, the contents are

AD User ID for 7.5  NW User for 10.0  

DOMAIN\USERA     USERB

USERA exists in BPC 7.5 and USERB exists in BPC10. But i cannot see the new environment when i logon using the web/admin. Not sure if unchecking 'master data' causes this?

Thanks for looking
