QSYS generate no bdf File

Hi there,

...problem with quartus. I use the free web edition and take the nios2/e 
processor.

I created a system with QSYS. After the generation I want to import the 
symbol in my quartus block-file,
 but there is no block from the created system.

In the generation-menu "create block symbol sign..." is crossed...

I give the whole project names without an space, only whole words...

Why does Qsys not generate a block file ?

Thank you
