trouble with path using SOAP

I'm struggling with converting URL access to SOAP access for security reasons. 
I used to code by Brian Larson - SQL Server 2005 Reporting Services.

When I build and attempt to run the report, I get an error on my path.  It's
less than 260 characters and I'm not sure why it doesn't like it.

Any ideas?

System.Web.Services.Protocols.SoapException: The path of the item
"/reportserver$sql2005?/634a6a2f-4138-4f6b-9f54-c44f1546f7bc/drug_cost_trac
king_by_protocol" is not valid. The path must be less than 260 characters
long and must start with slash. Other restrictions apply. --->

I solved my own issue.  You don't specific the report server path, just the
report folder and report.
