I'm using Microsoft Expression Blend, everything was fine but today I tried to open a project to keep moving forward and it will not let me open it. I miss a message that says:
Error opening (where the file is saved). The specified argument is outside the valid range of values.
I tried to open a new project to start over, but in the programming part you see everything blank and it does not let me write.
I had never made that mistake. The version is M.E.Blend 3.
