I have made some changes in my skin on my development server, and now want to export these changes to the production server. As I can't copy files directly to the production server, I want to do this by DNN-functionality, so by creating a skin package and export it to the DNN-site. How can I do is? The following steps should do the trick imo, but I get stuck at step 5.

1) Go to Host --> Extensions
2) Choose 'Create new extension'
3) Select type 'skin' and fill in all required fields.
4) Edit the skin by clicking the edit-pencil
5) Choose 'Create Package'
---->>>> This is where things go wrong! I CAN'T select this option for my newly created extension. The option is only visible for skins I allready uploaded. How come?!
6) After creating the package, import the skin package on the production server.

Can someone help me with step 5?! Or give me another solution?!
