Your chances of getting help would be better if you would contact UPS since it's their SDK.
I don't know this UPS SDK, but I had a look on the UPS-website
Is it zFirm's ShipRush-SDK you use (at the bottom of the page)?
], they have a quite active forum for users. Your chances of getting help will be higher in that forum than waiting for somebody who knows that specific SDK stumbling upon your question here.
modified a 2nd time:
Have a look here: zFirm-Support
]. Knowledge Base, documentation, technical support, training videos... (still assuming it's ShipRush you are using and not something else).
...and modified a third time:
Probably you downloaded one of the UPS Developer APIs
Did you have a look into their Knowledge Base
