Searching registration reports

[MagdalenaDaF]

Hello together,

I am trying to find my registration reports from Feb 16th to Feb 25th.

Unfortunately on Tuesday I changed the Meeting name (all the rest is same) from Modul 3 to Modul 4 and now all other Meetings before disappeared. How can I get the reports of the former meetings? I totally need them, and unfortunately really quick :-(((

Thanks for helping,

Madalena
