FL-300R both green & orange lights keeps blinking

Hi,

I got mine FL-300R early this year when I upgraded from E-p2 to E-p3 and I had been using it with great results and no problems ever.

However, when I try to put it on like usual a couple days ago, this problem of both indication lights came up blinking and didn't stop whatever you do, so I referred to the manual and it says that when these happens you need to change the batteries. But I had fresh batteries. Nevertheless So I did. Same thing continues.

Has the flash gone malfunction? Should I send it in or some one has some tips or tricks to set the flash straight again?

The last time I used the flash for RC purposes, like I did before that, no problems at all, if this might give some hints.

thanks for any input and info offered.

cheers
