That might already be the reason... as those can take a while. The Initial User Key will work for quite a while though. Wouldnt worry too much here.
After purchasing a MuLab User Key via PayPal, PayPal shows a confirmation page with a link "Return to MuTools.com".
By clicking that link you can instantly grab your Initial User Key that you can use immediately.
Note however that this Initial User Key only remains valid for a limited time.
Some days after your purchase, and certainly before the Initial User Key becomes invalid, you'll also receive your Personal User Key via email.
Make sure you also enter your Personal User Key as that's the permanent one.
