Hi Elisabeth, don't mix versions. There is lots of stuff that can go wrong (files that don't exist in 4.5 cross that the longitudinal stream expects etc.). Since the longitudinal stream has been improved significantly since 4.5 (more reliability, several bug fixes etc) I'd recommend to re-run everything using 5.1.
