Interesting problem who experienced this before

I bought XL about 2 months ago works great I wanted to try OS2 but had some issues installing it. so I tried to install the update using 3.09 and installing back XL112 now it says non compatiable AKAI OS?
who had this problem?

Now when I jump tothe upgrade XL114 it will not load just hangs?

stumped on this one and yes I did reformat serveral times

did you install the latest version of os1?

problem solved i did not have my all in one usb drive for the flash card.. works now
