Windows 7: user gadgets are not displayed in gadgets list

Hi guys.. I'm desperate and Need some help!

I developed a new gadget and put it inside Users\myUser\appData\local\microsoft\windows sidebar folder.
Everything worked fine untill I changed the .net solution file name (which is not part of the gadget files) ...

Now, it stoped working in my computer but same gadget files work fine in another computer.

Tried to delete the settings.ini file,
restart my computer,
remove and re add windows gadget platform from windows features,
Delete [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\]. key


Nothing helps !!!

Please Help :-(



Thanks Yael
