I now understand that the bundled LR does perish when one discontinues the subscription. This conflicted with Eric's answer in the affirmative when I asked if the bundled LR license is perpetual, i.e. that one could continue to use the LR one had from the bundle at the end of a year after discontinuing.
If the CC LR license does perish, then that is a bit scary since LR catalog files are not backwards-compatible. This could be a bigger problem than PS not being backwards-compatible. A single LR perpetual license upgrade at the end of CC is not a problem, as long as there are never any version restrictions on upgrading LR. I have LR 4 now. If I quit CC at LR 8 and the CC license perishes, I want to be able to upgrade from 4 to 8. If I have to upgrade the LR perpetual copy at every step along the way, it defeats the benefit of the bundle.
Can you clarify this one more time?
