I passed Level 1 4 years ago, enough time to pass II and III?

Hello, I enrolled into CFA program in 2004 and passed Level I in 2008. I heard that I have to pass all three exams in 7 years. But it seems that I have run out of time. Can I ask for an extension so I can take level II and level III in the next 3 years or even 4 years? Thank you.

The CFAI site says you can take as long as you need to complete the program: http://www.cfainstitute.org/cfaprogram/Pages/index.aspx
