This thread was very useful in helping me make my own c-gear skin. for those having the "skin data for c-gear deleted" error, the only way I found to make it work was to have a skin already.
1) Unlock a skin on the global link
2) Download said skin to your game (by connecting to the global link)
3) Then follow directions found earlier in the thread to replace the skin
If you don't have a problem replacing your skins, don't worry about it.
Also as a thank you, here is my custom Scizor skin for anyone interested.
