problems with equations in 2012 after instaling 2013 Beta 3

Hi people.

Am I the only one who is running into trouble with equations in SW 2012, after the Beta 3 of SW 2013 was installed?

For example:

When i try to create a global variable in SW 2012, i keep getting an error saying that the syntax of the equation is incorrect.

But before i installed Beta 3, everything worked fine with creating Global Variables in this way etc.
