individualize my system will upgrade IBX (click the Upgrade button or not)?

[mgxer]

I have WMP 11(v11.0.5721.5268) so i think i will be able to use "fu4m 1.3 fix-2".
I go to:
services.wmdrm.windowsmedia.com/indivSite/en/indivit.asp
in order to individualize my system and i get this message:



"The file or device you are trying to use requires a component of Windows Media Player to be upgraded.

Click Upgrade to download and install the required component."

I canceled so my IBX won't be upgraded(I wasn't sure).

Is it safe to upgrade or this will upgrade my IBX ? If it will update then what should i do ? how should i individualize my system?

thx
