I have an issue about the Error message: "Object reference not set to an instance of an object" from Trados Studio 2017.
I tried many ways according to solutions from SDL community. But all failed.
Even I bought a new computer and installed Trados Studio 2017, but usless.
And I tried Trados Studio 2021 and 2015, all has no issue. For upgrade to 2021, it takes money. How about downgrade to 2015?
Originally I bought Trados Studio 2015 and upgraded to 2017 without any cost. SDL recommended me to upgarde to 2017 without any cost at that time.
So Can I downgrade to 2015 the original one I bought?
