Change Lisence in Staad.pro CONNECT Edition from "Staad.pro Advance" to "Staad.pro"

How can I change this 

I was use trial version of Staad.Pro Advance Edition in Staad.Pro CONNECT Edition Then Trial License is expired

I open Staad.pro connect edition They pop-up "Staad.pro Advance - Activation Status" Dialog

if I click "Activate" or "Close" They alway pop-up another  "Staad.pro Advance - Activation Status"  Dialog with Product Activation Wizard

Then I check "Select subscriber activating against a host(Bentley) SELECTserver" Click next

I put Server name and site activation key then click Next, Then I check sign in later and Next, Then Thailand, Next, And Finish 

They tell "Your Product activation is now complete. You may use your product" Then Click Close 

The another Product activation wizard dialog still open  Then i Click close 

 

They pop-up Dialog "Staad.Pro CONNECT Edition" with note "Trail/Valid license was not found or license has expired! Aborting...."

I click OK Then Program Close

How can I fix this ?
