Error trying to mine with stratum

I'm giving a specific case here, but I think I have seen the same error trying to use stratum_proxy for any pool and coin I have tried.

When wemineltc.com briefly had a getwork server up, cudaminer worked great! But now that they're back to stratum only, I'm trying to get that to work.

I run the stratum proxy that I get from wemineltc and see this:

Then I run cudaminer with the following batch file (on windows 7 64 bit):

cudaminer.exe -o 127.0.0.1:8332 -O user:password

And see this:

C:\dev\cudaminer-2013-04-14>cudaminer.exe -o http://127.0.0.1:8332 -O user:

[2013-04-16 08:29:52] json_rpc_call failed, retry after 15 seconds

I have tried a few different things but I always get that 401 error. Any ideas on resolving this?
