Katalon new version get deactivated again and again & every time on reactivating its thrpows an error message

Katalon new version get deactivated again and again & every time on reactivating its thrpows an error message that username and password is invalid (however I am able to login on Katalon website with same url) or sometime its throws ‘Cannot connect to Katalon TestOps Server.Check your internet setting’ (However in this case I am able to access my internet on browser)

Apart from this there so many many problem with new version as after 15 to 20 minutes it get disconnected if u r not using it and also while running suite you will not get basic html report as well. I think Katalon team wants every one to get the licence one and not able to use free as there were no issues with 6 version and people r using more 6 version than 7 so they maid a statement that after 30 April u would not be able to use older version.
