I am currently learning or training the Tekla structure version 2021 from your Tekla campus. i have downloaded and installed the version on my workstation after having the account registered and verified. the first time i used it, it was working fine. the the next session i was having difficulty signing in. from then on i cant open the program. I have a trial version with trial license for 45days now i am on 15th day only.
is there any procedure to opening Tekla? (i have turned off all my security settings and firewall protection and i have tried to re install several times the version).
I am having on line class but i can only take down notes because i cant use the trial version.
looking forward to your support.
