Germany Federal

I am having trouble trying to update my collection for Germany Federal.
It will not let me in and when it does it will not let me record.
Other countries no difficulty.
Thanks charley716

Sometimes I forget to login to Numista and it will not let me record my entries...

Thanks 2 josephjk
I tried that and still no results.
I wish someone would try Germany Federal and see if it is my problem or Numista. charley716

 It works for me. I typed Germany Federal in Search and chose the coin below, then typed  1  in the Collection part under XF for 1975 D and it accepted that, also the Exchange part works.
 Is that what you are trying to do, please ?

  I guess you know a few sections were combined to make 'Germany - 1871-1948' on here; so there is no Weimar or Federal etc as such - or if that affects what you are trying to do.
  Can you give a coin page and details of your attempts.  

Thanks to all.
It is my computer. It is old.
Maybe it is trying to tell me something.
Will delay the rest of my collection until I get a new one.
