My PB wont switch on! I hadn't used it for about a month and now it wont turn on! Ive tried all the resets...holding down power button&volumme buttons etc and nothing! When the charger is plugged in the led light flashes red twice every 5seconds! Any ideas whats wrong with it?

A couple of thoughts:. Are you using the correct charger?  The PB will not charge properly with your phone charger but requires the higher-powered charger that came with the PB.

Also, your battery may be in "seal" voltage (below 2.8 volts) which requires connecting to a charger for up to 3 hours before normal charging (pulsing yellow light) begins.  RIM states that if you still have no response after connecting to a charger for 4-6 hours, attempt to force a boot by holding down the power button alone for 20 seconds.

Good luck.

The double LED flash - I got that once and had to do a recovery using Desktop Manager. Luckily I had a recent backup.

Ive plugged it into desktop manager and it says 'blackberry desktop software cannot communicate with device'

Connect the PlayBook to your PC.
Launch Desktop Manager.
Hold the power button on the PlayBook down for 20+ seconds (the flashing should stop).
Keep an eye on Desktop Manager. If it doesn't give you a repair prompt within a minute or two, press the power button on the PlayBook.
If nothing happens still, or you get a "cannot communicate" error, try again.
