oracle window

I can't use "Oracle database" option to get the data. It was working fine...I was able to copy and paste SQL script from Toad and load the data. But it's not working any more. I uninstalled and reinstalled the program (used 32 bit....64 bit sometimes create problem in my machine) but still the same issue. I go to "Get Data" and click "Oracle Database" and "Advanced options"...this section is not opening and crashing the whole Power BI program. I need to go to Task Manager to kill the program. Please let me know how to get the Advance section back so I can use SQL to get the data.
