DHT11 Woes

Just tried grounding pins 3 &4 together -- same result

running the library from Arduino Playground - DHTLib
it returns bGlobalErr = 1 (Start condition not met)

if I disable that section then it spits out Error 3: DHT Checksum Error

beginning suspect the Arduino Uno I'm working with may be faulty as I've tried 2 different DHT11's and get the same result

any other ideas to debug are appreciated
