forget to eject game disc when install CFW 4.30, not it shows 4.31 in system info

I am having trouble with my ps3. I was on CFW 3.55 and I tried to install CFW4.30 today. The mistake I made is that I forgot to eject the game disk (sports champions came with the ps3 when I bought it 2yrs ago). the ps3 still boot up and when I check the system version, it showed 4.3.1 at this time. Is there any easy fix for it? Any advice is appreciated.

thanks thanks
