When I got x9, I had both the 32- and 64-bit versions. I didn't use the 64-bit because it did not support 32-bit plugins.

If I download both X10 32-bit and 64-bit and then decided to upgrade, would I need to pay for both? I'm a little nervous about this because (judging from some posts here), the "newest and greatest" installation files are buggy.
