Hello,

Please help, I have a serious problem with SDL Trados Studio 2011. When I try to open the program, the following error message appears:

Invalid digital signature - The licensing component could not be authenticated. Possible causes: - The licensing component has been modified - The Root Certificate Authorities store is out-of-date. This can be updated through Windows Update.

I have followed the steps that are explained in the knowledge database, I downloaded and installed the Windows Root Certificate Authority Update, the latest I could find was for March 2014. I installed and rebooted, but the problem remains. I even uninstalled and reinstalled Studio, but it didn't help.

Last night, everything still worked fine, I didn't make any changes since then, it suddenly just stopped working this morning. Multiterm is still working normally, and all my other programs are also running fine. I'm using Windows XP SP3.

I can't even deactivate the license in Trados, it's completely blocked.

Thank you for your help!

Michael.
