Vaughan, below is what your dnetc.ini file should look like, other of ocourse than the id= line which should reflect the email addy you are using for the project. You can use notepad to edit your dnetc.ini file to look like the example below. You don't need anything else in your dnetc.ini file. It will then load up 25 work units per core and start crucnhing and should run all the way through those and then re-connect with a distributed.net proxy and dor the up/download thing. If your executable file doesn't recognize the parameters in this example dnetc.ini file, then you are using the wrong executable file. Let me know and I will email you the correct one.
