How to change the date's configuration on NAV 2009 r2

SabrineMISSAOUI

Hello,
I'm creating a project and when i'm trying to change the date of start & end, this error is displayed:

in the current entreprise,for which the date entered is not in the allowed range

and the filter is : "??11*|??12*|??01*|??02*" which is defined in the license file

PS: my license is MSDN

Can someone tell me please how i can configure and change the filter on license file concerning the date?

Thank you for your help

You can only enter dates in November, December, January, and February with MSDN license
