[V8i] Bentley Fiber Installation: Unable to go to 'LIVE' workspace in ORACLE

Hi

I've just installed Bentley Fiber, but I'm unable to create new designs. This is the error that I've collected from DBWin:

7920: GotoWorkspace SQL - DBMS_WM.GotoWorkspace('LIVE')
7920: Desc - [Oracle][ODBC][Ora]ORA-00900: invalid SQL statement

7920: Error - IDispatch error #3092
7920: CCHCustomWorkManager::CreateWorkspace() - Error
7920: CCHError::GetDisplayMsgParam()
7920: CCHError::Reset()
7920: ERROR: [e:\Builds\exdc081109858\Source\Utility_Applications\ExpertDesigner\ED\CHGraphicalUserInterface\ExpertDesigner\WRListView.cpp - 2217] - CWRListView::OnCustomAction(UINT uID).....

I've tried running the DBMS_WM.GotoWorkspace('LIVE') package in the database, but it throws an error stating that the 'LIVE' workspace does not exist.

BEGIN dbms_wm.gotoworkspace('live'); END;
Error at line 1
ORA-20122: workspace 'live' does not exist
ORA-06512: at "WMSYS.LT", line 7303

... but I DO SEE the 'LIVE' workspace in there:

SQL> select WORKSPACE from WMSYS.WM$WORKSPACES_TABLE where WORKSPACE = 'LIVE';

WORKSPACE
------------------------------------------------------------------------------

LIVE

Any ideas on what could be wrong here? Thanks in advance
