pay attention or don't care

[Attila]

Hi All,

If a user starts the program a message pops up where he can click OK and the window is gone.
For the user, the message isn't important at all and it isn't worth to read it.
I want to write him to click OK and forget it.

1. A message will appear but don't pay attention to it.
2. A message will appear but don't care about it.

which is better?
Is there a rougher expression for that situation?

I think (2) is better. (1) sounds like if you pay attention to it you will get into trouble.

How about 'Just go by the pop-up message' for a rougher version?
