Error with file of core SC 7.1.

Hi, i am generationg an application and sc show this message:

Fatal error: Call to a member function GetTag() on a non-object in C:\Program Files\NetMake\v71\wwwroot\scriptcase\devel\class\generator
mFontePHPForm.class.php on line 12347

Invalid argument supplied for foreach() | Script: C:\Program Files\NetMake\v71\wwwroot\scriptcase\devel\class\generator
mFontePHPForm.class.php linha: 12045

This is a SC file and it does not opened. (Encrypted).

I have opened other forms and all show the same error.

Maybe session expired in dev enviroment?
