Problem with Grid

When I run a “grid” I get this error:
Fatal error: Uncaught Error: Call to a member function GetData() on null in C:\Program Files\NetMake\v9\wwwroot\scriptcase\devel\class\interface
mConnection.class.php:228 Stack trace: #0 C:\Program Files\NetMake\v9\wwwroot\scriptcase\devel\compat\compat.inc.php(752): nmConnection->GetAllConnections() #1 [internal function]: unknown() #2 C:\Program Files\NetMake\v9\wwwroot\scriptcase\devel\compat\compat.inc.php(2): sg_load(‘CE7E8A614756C85…’) #3 C:\Program Files\NetMake\v9\wwwroot\scriptcase\devel\generator

This happens to me if I make a new grid or run an old grid.
I tried to make a grid with a new project, but I did the same mistake.
Are there some people who can give me a solution?

I would tell that this problem I did not have it with the old version 8.1 of scriptcase.

Thanks.
