Possible to increase matrix size?

[ROSSINL]

Hello,

I ran into the following error:

"Matrix size error: too many parameters for default coefficient vector"

I have an enormous amount of dummies and interactions between dummies in my specification, so the matrix seems to small. Is there any way to increase the matrix size in Eviews 6 and if yes, how?
If not, is the matrix size of Eviews 7 larger?

Thank you in advance!
