Hi,
I seems that several people are having this problem. I think it still has to do with the buggy 64 bit drivers. For some reason, on some systems, the driver is not installing correctly. As for the uninstallation error, thanks for posting the log. I just realized that there is a bug in the installer.
I am planning on rewriting the custom driver in the next 3-4 weeks. After that, I will most likely move the project out of beta stage.
Sorry for any problems and thanks for waiting.
