Problem of drag and drop between cubase and groove agent 4

Hello I just installed Cubase Artist 8.5.10 64bit on windows 10 64 bits.

Impossible for me to drag and drop a pattern of groove agent 4 SE in a midi track .
I followed the procedure in the manual and the advice of a french forum but nothing works.

I can drag and drop by against a windows audio file in cubase.

Can you help me please

(Sorry for my English, I’m French and i use google traduction)
