For every project for the client to accept you for the job they need to prepay it. You should've received an email along the lines of "Congratulations! Client selected for the job and prepaid x amount"
Once they have prepaid it the money is held with cgtrader until the client marks the job as "complete". Then you'll get paid!
Send everything through the website and even if the client forgets to mark it as complete (which can happen) cgtrader will step in and mark it as complete for you.
All you have to make sure is that they have actually selected you for the job and prepaid it. Once that's the case just send the finished files to them and rest assured that everything will be sorted out one way or another.
Hope I explained that clearly enough. IF you have any questions just ask.
