Incompatible srt file

Hi everyone,

I got a bunch of srt files to translate from a customer, and I was so happy when I found this plugin, but unfortunately when I tried to open a srt file, I got the message that the Subrip version used to generate the file isn't compatible. Since I don't have access to vob or any other files, just these English srt files and videos, is there a workaround to solve this?

Many thanks in advance for your help!

Best regards,
