Aegis Client Secured Wireless.....

I have an I8500 with the standard wireless internal card.  I downloaded Aegis Client software to be able to access my school's wireless internet, it is secured.  Before I had this software, I could access unsecured wireless connections by clicking start, then connect to, then wireless network connection.  Once there, I could click connect and it would work.  Now, with this software, the connect button is grayed out.  Does anybody know how I can fix this?  It is great to connect to the system at school, but now I can't connect to other wireless connections that dont require authentication...

Any help would be appreciated.
