The command "Import Animations from Reloaded Character" refers to characters from old TGC model packs.
These characters have the similar skeleton to old FPSC Reloaded characters. GG characters have new skeleton and that means that you can't import animations from GG character to character from old TGC model packs. I can't fix it because it's not possible to import animations for so different skeletons.
But there are other commands in Animer that can be used to import animations from GG characters to any characters with the similar skeleton, for example: "Import Animations from DirectX or DBO File".
ANIMER - Character Animations Editor.
