The segment is invalid. It could not be retrieved."

Question

I am getting this message when trying to open packages for a specific project: "The segment is invalid. It could not be retrieved." I've worked in this project profusely in the past (as late as last week), and have never had a problem. Any ideas on how to deal with it? Thank you.

Thank you for your answer. As you can see, the request was placed 3 months ago. By now, I can't remember if it was the package or the project. I had to switch to Studio 2015 (from 2011) in order to solve the problem.

Hi Susana, 
 
Are you repeatedly opening the same package or do you mean Project? Also what version of Studio are you using? 
 
Regards

Trados Studio > 1. Trados Studio
