FreePBX FaxPro Will Not Send New Fax

Thank you both for the prompt reply! Before I switch back to Asterisk 11, do either of you foresee a problem in my other issue: [UCP Call History Not Able To Play Outbound Call Recordings or Download Them][1] which goes along with Issue ticket: FREEPBX-8233 and switching back to Asterisk 11? Mr. Andrew Naggy had been helping me with this and what I have gathered from him is that my CDR has been corrupted by Asterisk 13. So I was concerned going back to Asterisk 11 might make things worse all over…but hopefully I’m wrong.
