Need a bit of help finding something

Well two things actually.


I was wondering where I can find the file to change the text "An invalid currency was selected." when you fail to select a payment option and just click 'Order' under the paid subscriptions area.


Also, can someone tell me what file to change so that whenever someone who doesn't have privileges to access a certain area, instead of seeing a blank screen with no posts they see something like this:

Thanks everyone
