error in Dynamics AX Reporting tools

Hi everybody,

I appreciate somebody can help me to solve, what can I do when in Visual Studio 2010 open a Dynamics AX Model Project and always in the output screen shows the same message?

: message AX1053: The model file was saved with an old version of the Dynamics AX Reporting Tools. Saving the file will also update its version to the current version.

Thanks a lot in advance,

Josep
