Hi,

If you are using the same GME version to create all of your mga files 
and GME manages to open/attach an mga file with a different/older 
paradigm, then you should not expect any problem (ie.: you can submit a 
bug report if problems occur later...). In these cases the MGA layer 
checks the entire project before opening it.
