Importing Reviewed Texts

Hi, I have a 5000 segment text (each segment only has a max. of 3 words), it was sent for bilingual review. Now I cant re-import the text and update the Trados file. There must be a better way than having to copy each line out of the reviewed text and paste it into Trados - That would take hours!! I am new to Trados and would really appreciate some help!!

Thanks!
