New user needing advice on 'Effects'

The Many Cam Effects folders seem to have disappeared from the menu except for the ‘Unordered’ and ‘Gifs’ folders.

I can find no advice on this issue in the Help pages or Google so I uninstalled the programme once and I got all Effects folders back but then Many Cam crashed again and I lost all the Effects except the same 2 folders. I have uninstalled and then re-installed again and this time the solution has not worked. Still only 2 folders visible.

What am I doing wrong? I am on a new work laptop. I want to use many Cam for teaching so as a new user I would really appreciate advice. I have a ‘Standard Annual’ account.

Thanks in advance
