This beta version has expired

I am developing monodroid application an开发者_JAVA百科d everything seems to be working fine [I was able to run the android project before] till one fine day and suddenly I got this error message while running the android application from VS2010.

Than I downloaded the monodroid installer from here http://go-mono.com/monodroid-download/ and when I tried to run it I am getting the below error

I am confused. How to resolve this error?

MonoDroid isn't free, you need to license it. Sounds like the license expired.
