SSRS 2008 subscriptions have incorrect data - sql-server

Question

I have written, and rewritten, a hospital census query for which I would like to create a daily Windows File Share subscription. The query seems fine; it runs properly in SSMS, BIDS, and on the SSRS Report Server itself. However, when I create any kind of subscription, sometimes the report will have old and incorrect data on it. There is no real pattern to when the report generates incorrectly, as far as I can tell, but the data that gets sent incorrectly is consistently the same, and is from back in January. I had initially written the query on a test server with the same data, just a little bit older, and had changed the dates that it would run for. I also had to re-deploy the report a few times after making changes. I had initially deployed it from the test system directly to the live server, so I tried completely redoing it in the live system, in addition to making some changes improve performance, but I am still getting the same incorrect data.
Any ideas would be greatly appreciated at this point, because I am at a loss and I am really just getting started with SQL.
Thank you for any assistance.
Edits: adding the queries that are returning the inconsistent data; removing my comments that have poorly-formatted code.
Also, to be a bit more specific about the issue: The subscription sometimes sends the census data for the day before as expected, and sometimes it sends the census data from January 15, and this only happens in the subscription.
Query 1:
SELECT

,V.AccountNumber AS AccountNumber
,V.FinancialClassName AS FinancialClass
,V.ServiceDateTime
,P.EmergencyID AS Provider
,X.ErDateTime AS Discharge
,X.ErDispositionID AS Disposition
FROM dbo.AdmVisits AS V
INNER JOIN dbo.AdmProviders AS P
ON P.VisitID=V.VisitID
INNER JOIN dbo.AdmDischarge AS X
ON V.VisitID=X.VisitID
WHERE CAST(V.ServiceDateTime AS DATE)=CAST(DATEADD(day,-1,GETDATE()) AS DATE)
OR CAST(X.ErDateTime AS DATE)=CAST(DATEADD(day,-1,GETDATE()) AS DATE)
ORDER BY V.Name
Query 2:

Answer 1

So it turns out that the issue was the data source's connection string to the server. I was using 'localhost' instead of the server's actual name, and since the test and live servers are basically clones of one another, I think it wasn't consistently connecting to the right server. Not sure how exactly that works, but the report is working now.
