I've seen those problems in the past when an installation was not okay. Most of the time BTS was damaged. But here I'm not sure. The TradeUtil is a part of BUG and so part of CCV. Please try the new version 4.29G. It would be good if you could remove the old CCV version manually by deleting the Community Civ V folder in Beyond the Sword\Mods\ ! If you still got trouble after the installation of the new CCV version please follow this routine:
i) deinstall BTS and CCV
ii) check manually that all components have been really removed
iii) install BTS 3.19
iv) run CCV 4.29G installer
v) Try it again!
And here the change log of the new version:
