HTC Hero :: How To Tether Phone Using Pdanet?

Ok, first of all I am using one program right now called "easy tether" but i had pdanet and it worked fine on the trial part, that expired and I tired to connect to it and kept getting an error code "633" so I thought it was just because it was the trial program and not the real thing so I purchased the damn thing and I still can't get it up and running. I didn't mind paying for it as I said it ran pretty good before and just thought I would stick with it but I can't seem to get it up and running. I downloaded the easy tether and it runs good too but since I paid for pdanet I would like to at least try and see if I can get it up and running so can anyone tell me what I might be doing wrong by getting that code? If I can't get it going I need to request a refund and I am out of town right now and that is why I need it so I can access the internet while I am gone, I can't go a month without internet!!! So can someone try and explain if they can what might be going on for pdanet not to run. Like I said I am using the easy-tether right now as we speak but it is a trial version too so don't want to have to pay for another one to avoid not being able to access secure sites.
