Can’t connect to Salesforce using Crystal Reports 2008 SP3

Hi, we are trying to create a salesforce connection in crystal reports and have not had any luck. We go through a proxy server to access the internet and I am not entirely sure what should be entered where.

In the crystal reports connection string SalesForce logon:

Should the Server stay as www.salesforce.com or point something else like the instance?

Should I append my security token to my salesforce password?

From what I have read we need to make adjustments to the CRConfig.xml if we use a proxy

For the proxy address, should it be http://<proxy server name>.com?

For the proxy user name, should I include the domain? Domain\usersname?

Any help would be appreciated as I am under a time constraint.

Thanks,
