Can't format memory card.

[Denisowator]

So I just emulated Sly Cooper and the Thievius Raccoonus for the PS2, and when the game starts it says that the memory card wasn't formatted. It then asks me if I would like to format it, but the problem is that it's stuck on "No". I literally can't do anything to switch it, I tried clicking on "Yes", pressing buttons, but it's just stuck on the "No" option. I even tried configuring the entire controls to my keyboard.

Someone please help.

From the pcsx2 menus set CDVD to No Disk and then use fast/full boot to enter the bios.From there go to the Browser and format the cards
