Traktor Pro questions (easy ones)

Hello long time with out ask anything:
My first question is about how many times can you install traktor in different computers? I mean can i have it on a pc and in my laptop?

And how to use right the grid points (¿are the white bars in the track?) in the songs that I've used most of them are in the correct position (on the beat)
but sometimes they are not, so.What do I have to do? Mark the first one on the beat and move the others until get them where I want?
THANKS!

1) 2 instances.

2) There is a video by Ean on how to correct grids and adjust them etc.

Check the FAQ.....

You can install Traktor on two computers. Read this for beat gridding http://traktorbible.com/en/tutorial2.aspx There's also lots of youtube videos out there showing you how.
