Welcome to the forum.
On the activation issue, see
this
post.
You started by saying that you are having trouble with CHM
files not working with XP. Do you mean when they are located on a
network drive rather than on a local drive? If so, see
this
post.
If it is something else, post back.
Obviously you are unlikely to get the activation thing sorted
today but it should work without activation for one week.
