[SOLVED] cannot create category

[grafica]

Hi, I've installe Phoca Download on Joomla 2.5.17.

When I try to create a Category I get an error message alerting me that the Category cannot be created because: CATEGORY MUST HAVE A TITLE.

Of course, I've entered a title in the proper field. Any idea on the possible cause of this error?

Thanks in advance.

[EDIT]
Reinstalling the Component. fixed the problem. Thanks.
