Cannot find test data with id/Cannot connect to Oracle SQL

After updating to Katalon 7, I am getting an error for my Data Files:

Cannot find test data with id ‘Data Files/My Data File’ because (of) ‘java.lang.IllegalArgumentException: Test data missing ‘driverClassName’ element’

Everything worked fine before version 7. I even tried to make a new data file, but I can’t because now it says: Connecting to Oracle SQL is only available on Katalon Studio Enterprise.

Does this mean that I cannot make any database querys anymore? Would be VERY disappointed if this means that I can’t run my project anymore with Katalon because of this error.

what is answer for this issue ?
As I am also facing same issue with katalon.
