Hi Gainsight community!

I have an active play. For next e-mail chain (e-mail #2) I had to update some contacts. I added the new CSV with the new contacts but deleted the old one. Now when I upload the new one, the contacts don’t show. 

I have 3  questions:

1. Is it bad to delete a CSV when it’s active?
2. The participants in the current CSV (the new one) don’t show. Do you know why and how could I fix it?
3. If I delete a CSV, does it mean that the e-mail #1 will be sent again?

Thanks in advance!
