Problems with registering after Firefox rebuild

: Function ereg_replace() is deprecated in /mozdev/sandbox/php/include/globals.h on line 95.

Lost all my FF settings and had to redo the FF installation from scratch. SIGH!!! All is done now about from Foxy Proxy Plus. 
As usual, this stops FoxyProxy Plus from working... I have an existing premium proxy subsription and bought a Foxy Proxy Plus licence. I don't know what the problem is, but the browser is now refusing to surf when the proxy is enabled (it has not expired).
I can't find the part in Foxy Proxy where I'm supposed to re-enter the reg details. Please can you give me some advice how to troubleshoot the problem?
 
 

Forgot to say that FP Plus

Forgot to say that FP Plus now displays as FP Standard. Obviously it has "unregistered" itself somehow. I believe I still have the reg details but where do I enter them?
Or do I have to download FP plus from somewhere? I am beginning to guess that there is quite a tight lid on the paid version and this is the reason why I now can't use the software.
My email   johanna.nes     at   gmail  Am a legit customer and want to use the software. Should it really have to be this complex just because you have to reinstall the browser and plugins?

Thank you, I have now

Thank you, I have now re-installed the client. Would have preferred if this could have been done without a visit to the support forum. MY PATTERNS HAVE NOW STOPPED WORKING THOUGH. I don't know why, I haven't changed them. I cannot use the "Use Patterns based on pre-defined patterns and priorities" any more. But I have not change anything and I can still see the settings. So far as I can tell they are still there. The setting is simply use the proxy for most regular sites (filter is just a star, always worked fine) and my real IP for things like Paypal and various sites that ban proxy servers. (For this, I give the URL for the sites that I want to use my real IP.) This has not changed and I can still see the settings. It works if I force set Forxy proxy to use the proxy but this is invonvenient since some site I use do not accept proxy servers. How do I get the filters to work again. Sorry if I sound irritable, this is very irritating and it wasn't more than a few months ago since I last had to re-do this...

EDIT: Found the problem; settings had been PARTLY changed and Foxyproxy tried to use TOR instead of the premium proxy.
