SCLogin module's bugs

Hello!

For my web site (www.venturaluca.com/jupgrade2) I have installed:

a) Joomla ver. 2.5.14
b) Latest version of "SourceCoast Social Bundle" (JFBConnect 5.1.2 and JLinked 2.2.0)
c) SCLogin module (ver 3.1.2)

I installed SCLogin modue in the headerbar (top-right corner) of my Yootheme template. I have some problems with SCLogin modules:

a) If I use "Modal PopUp view" in my home page (www.venturaluca.com/jupgrade2) doesn't appear the pop-up window when I push the button "Accedi" (Login in) to authenticate to my web site;
b) If I use "Always visibile" in login view settings there are two problems in the home-page. First of all an image icon doesn't appear ( I suppose is "Facebook"'s image icon) in the SCLogin module's front-end: the related link seems to be broken, in fact a question mark "?" appears instead of the image icon. Then if I I click on the question mark ("?") the login facebook window appears: I insert the correct credentials but nothing happens!! (no authentication process is executed). Why?
c) If I enable FBCSubscribe component ver. 4.2.0 (I called this module "SEGUIMI SU FACEBOOK" in my Joomla admin panel) of JFBConnect I obtain the following PHP Error:

ATAL ERROR: CALL TO UNDEFINED METHOD JFBCONNECTPROVIDERFACEBOOK::GETUSERID() IN /HSPHERE/LOCAL/HOME/VENTURAL/VENTURALUCA.COM/JUPGRADE2/MODULES/MOD_JFBCSUBSCRIBE/MOD_JFBCSUBSCRIBE.PHP ON LINE 20

Is there some incompatibility between SCLogin and this module?

If you want I can send to you in private (let me know you account to which to send this information) all the data to access my Joomla admin panel and check by yourself the problems above.

Let me know,

Thanks a lot,

Luca

ps. I posted the similar request in SCLogin forum...because I need to solve these problems urgently!!
