I have installed K2 blackpearl 4.6.8 and built k2 project with Microsoft Visual studio 2010. Previouly, it is working file, I can deploy k2 project.
But last week when I opened the project, showed the error 'D:...Myproject.k2proj' cannot be opened because its project type (.k2proj) is not supported by this version of the application.' and can't opened the project. I tried to find the root cuase but I can't.
So I would like to know how to fix it. I remove k2 blackpearl and install back again also got same error.
please help me.
Thanks.
