My trial is over, but I can still use the LR version I have downloaded from the LR CC web page (I couldn't see the LR 6.3 button initally). I assume the version is 6.3 because I got an update while running the trial version of LR CC and the new version has the "Classic" import image menu, which became available in the 6.3, the latest version.
I assume that all of the above is, in fact, true??
If your trial is over you can not use LR anymore.
And about the import in Lightroom, we came up with a new import interface which has been reverted to how it looked earlier in the version 6.3
