Lost my ODBC within Powerbuilder 12.5

Having recently installed PB 12.5, everything was working well on the Claasic side. After installing a 12.5 application executable over SQL Anywhere 12.0, within the Powerbuilder environment, I suddenly have lost my ODBC database interface. I am on a 64/32 bit machine. Does anyone have any ideas how to get my ODBC back? If I open ODBC Data sources from the control panel, everything is there.

Thanks,
