Hmm,
A lot of stuff will fall under 500 lines, but i am not sure if that's the true limit, and may be less,
especialy if there is loop or canned cycle in the file.
There is no time limit on the license.
Th only update being done is to update the Turn Module which will eventualy replace
LazyCam (LC) turn with LazyTurn (LT), and the LC license will be good for LT.
