Error when updating from bilingual review (translator has 2019 & reviewer 2017)

Hi,

I have Studio 2017 FL Pro and my colleague has Studio 2019. She exported a large file for review (304 pages), she sent me the liff, but when I click on the target and change even 1 word with TC on, she cannot import it back to her Studio. She gets this error: File contains corrupt data.

Thanks in advance for your help.

Be safe!
