Trados 2019 lags

Hello,

I have 2 issues:

 

1) Trados Studio 2019 lags at times while moving from one segment to another. It uses about 25% of the CPU in these moments and sometimes takes 10 mins to move to the next segment, even simple segments with few words, no tags and only a local TM.

2) I can't upgrade legacy 2007 TMs. I get an error saying files are missing!

 

Any help would be apreciated.

 

Best regards,
