1.52 and gold projects

two questions: 1. i went to gold (which i thought i paid for, though not 100% sure) and found no place in menu to check for updates so used the url given. only after downloading it did i see i should have deleted gold before downloading. should i delete the 1.52 , delete gold, then redownload?
2. not sure where to find info on transferring existing work in gold to 1.52.
thanks for your help and for creating the software…
