error in power query & power pivot

Hi,
i am new to power query and power pivot, i am using excel 2016 and got the following error when trying to combine two tables in query from table in data tab.

"we couldn't get data from the data model, here is the error message we got; No error message available, result code : -2146233052(0x80131524)".

I tried a lot but not found any power table add-in in excel 2016. there is only one com Add-ins available that is Microsoft Power Map for excel.

Power pivot is working but Calculated fields are not working and become grayed.

Please help

Thanks for quick reply

Get and Transform is available in my excel, i am using Microsoft excel standard 2016
