KL25Z bootloader fails / win 10

Hi everyone. I've been trying to enable my FDRM KL25Z board but I ran into a problem with the bootloader. Once I downloaded the last "openSDA" firmware and downloaded and installed the Windwos USB drivers from PEmicro page, I copied and pasted the openSDA application in the USB drive (BOOTLOADER), as the instructions say. Then I unplugged the USB cable and plugged it again (but now without pressing the reset button) and the PC didn't recognized it and the indicator LED blinks 8 times and then stop for 2 sec, that indicates an Error.

I tried this several times but I couldn't make it works. Probably is good to know that I got this FRDM board already used (I bought it to a person who used it to make some projects and it might have some code writen) but is the first time that I plugged in my computer. My computer has the windows 10.
