freemcboot problem...help!

Hi heveryone!
i have just installed freemcboot 1.8 on my memory card ps2. Now i can't play game disc with this memory card anymore! When i don'nt use this memory card, disc game run normally, but if i insert it, screen on TV appear "freemcboot" and then freeze. how can i play a game disc with this memory card? Do This memory card no longer can use to save games? if so How can i remove freemcboot from this memory card?

it cannot be used for booting original games. Burned games have to be patched before they can be booted using freemcboot.

so now i can't use this memory card to play games disc?
