Trados update 2019 to SR2

Dear sirs,

I tried to update my Trados 2019 SR1 to Trados 2019 SR2, but when I do this I see the next messagge:

An error uccured and the program was aborted. You can try running the program again but if the same problem repeats, please generate a debug log (usually found in C:/Program Data/SDL/Chainer/Logs) and contact technical support.

XmlException

Root element is missing.

Can somebody help me?

Thanks in advance.

Regards,

Vidak
