Material lybrary flamingo 4.0 is not working

Does anybody know why i can not change my materials anymore.

Im using rhino 4 and flamingo whith windows 7

The material library location is probably within the program files folder and is set to read only. This can happen in Windows 7 with User Account Control turned on.

The solution might be to create your own library and start your own material? The customer library should be created in a publicly accessible folder.

Im not able to open another library. I’m still getting refused word in my display…

Do you have maybe another solution?

also the strange thing is that it works ok in rhino3. Only in rhino 4 it is a problem

This is not working also sadly…
