Invoice notifications not coming through anymore

I recently installed the Sales Report add-on and it worked fine, however, it is just the time when the invoice notifications stopped coming in. If the purchase is more than $0, i do get a Paypal notification, but if the customer downloads a freebie, or something with a coupon making his/her purchase down to $0, i have NO notification at all.

Since i thought it was the Sales Report add-on that caused that, i had removed it completely, but that has not solved the problem, so maybe it was not the problem in the first place, but just happened to be at the same time.

Anywhere i should check to see if i might have accidentally changed a setting? I dont have a clue where to check.

Thanks

You might start by checking Configuration -> Email options to make sure everything is set the way you want it.

Can you send yourself an email from Tools -> Email?

It looks like that Email options are set properly, and yes, i can send myself an email from the Tools > Email.

Any other thing to check for?

On the same note, since i like to keep track of all the invoices outside the cart itself (meaning in my emails), is there a way to send myself a copy of the invoice that i should have received from zencart? I can deal with resinding them to myself manually for the time being as they are not too numerous.
