I think the first error might be the cause of the second. I just updated the installer to try to fix it. I don't have CS6, so I can't test it directly.
Please reinstall either Data Bridge v2 or ECart to get the updated file. It shouldn't matter which one. The order of installation is not important either.
Let me know if that fixes the problem. If not, I'll probably need to do screen sharing to reproduce and debug this on your machine since I don't have a copy of CS6 to test with.
