Blank page from admin panel after installing [SOLVED]

Hi, I have installed the latest version of ChornoConnectivity on my Joomla 2.5.9
After installing, where I click on Connection manager, a blank page is shown using FireFox.
With IE, instead, the message "Page not found" appears.
How can I solve the problem?
Thank's

Hi phpisoft,

a) Make sure that you have the correct version of CC installed for Joomla! 2.5

b) Temporarily set Error Reporting to Maximum in the site Global Configuration and see if you get a more helpful error message.

Thank's for the interest...I have solved installing also ChronoForms and it works...Is it right?

Hi phpisoft,

Yes that's correct, I forgot about that one.
