How to replace the images in a toolbar addin?

Hi all

I've a problem with a SW addin and VB. NET. I've created a CommandGroup, add my functions with AddCommandItem2, but I've put the wrong index for the bitmap

I've launch the addin, see my mistake, correct it. But now each time I start the addin I've the wrong icon in the toolbar.

How can I remove this mistake.

Thanks for your help
