All right guys, thanks for double checking. We found two new primes, I confirmed them here as well:
2955*2^406658-1 is prime! Time : 285.531 sec.
2775*2^408874-1 is prime! Time : 286.881 sec.

McDuck found and reported in February 2009:
2865*2^403368-1 and
2775*2^407228-1

but he didn't complete his range (or couldn't post them, for some reason).
