My application is self signed with a strong key. I don't remember the password. After 2 years of running and compiling perfectly, visual studio 2005 suddenly demanded to know the password for the strong key in the project before it would compile. Its never happened before but now it won't compile without turning off the signing entirely. Other projects have the same key and work perfectly. I tried to remove the old key using 'exclude from project' and to re-make a new one. It still demands to know the old key password when I compile. How can I remove the old key from a vb project so they I can make a new one? The help on the specific error goes to the page "...not every error has a help...
