what usually happens upgrading the version of RhoElements you use, is that you've to update the build.yml file to point to the new sdk version.
Could you please check that your build.yml file includes the line:
And don't forget to clean the project before rebuilding it.
From RhoStudio, setting the Run Configuration with a "clean before build", or from the command line with the command
where <platform> can be "android", "wm" and so on.
