usps shipping v3 displaying incorrectly

[flapjacks]

I tried getting the USPS shipping module v4.2 to work on my site, but it never shows up. With 'Show standard shipping options on error or no USPS results?' selected, the standard shipping options show up. Without it nothing shows up. In debug mode I see I am receiving correct XML back from USPS, but still nothing shows.

I went back to v3 which has been working fine.  However, recently it has been showing '^®' either at the end or sometimes in the middle of the shipping result name.  In v4.2 this can be fixed as shown here:  http://forum.virtuemart.net/index.php?topic=79926.0
v3 doesn't have this line of code to be edited so I am not sure how to get rid of this.

Any ideas on how to fix v3?
Or on why v4.2 is simply not showing up?
