I installed 3.40 OE a few days ago

and Ive just noticed that when I go into Recovery

and select Configuration, I get a blank light blue screen.

Then I have to power down the PSP to get out of it.

Ive tried reinstalling the OE, but I get the same thing.

Ive also downgraded back down to FW1.50 and then reinstalled

3.40 OE (DLed from a different source), still the same thing.

Any ideas guys ???
