Search for and check that thread I mentioned earlier and you'll see. Basically, you end up cutting your data rate in half by changing all the 1's to '10' and 0's to '01'. Sounds silly but it works great.
I got my RF module to work...I was using the +VCC from the USB port to power the receiver and that was causing some continuous ripple

I used a battery supply,connected the grounds,used a 0.01uF decoupling cap and now it works..

Thank you guys for your suggestions...
I will post the complete project once the VB.net Code is complete..
