Trying to update Pro from 11.0 to 13.0

[Tong Yew Meng 0]

Dear Sir;

My copy of Pro somehow becomes a Trial after attempting to update to version 13.0 from 11.0.

I paste on the serial but to no avail.

How this can be fixed? Appreciate your help. Someone in the community may have the same problem but I did not manage to go through all the postings and responses.....
