Download of RMSNT Failed from server...

I'm a new user to Sophos and am trying to get it working, however I'm having issues with it updating.  The error message I'm getting is as follows (note main IP has been renamed to X.X.X.X):

Code 0000006b:  Download of RMSNT failed from server http://X.X.X.X/CIDs/S014/SAVSCFXP/

After doing some google searches I found a site that advised changin a setting for the Indexing service (basically adding an exclusion to not look at the cache folder under the Sophos main directory).  I add this in, but still receive the above errors.  I'm not sure where next to look to resolve this problem.  Anyone have any ideas for me?  Thanks in advance!
