Unable to claim my purchase through your webstore

[B01000100]

I was unsure where to post this but it is a technical issue regarding my purchase of The Penumbra Collection so... I purchased the games through your own webstore and paid with PayPal. I was redirected to the invoice and it was also sent to my e-mail account. The e-mail instructed me to claim my purchase at: shelf.frictionalgames.com
I enter my e-mail address (the same e-mail I use with PayPal and thus also the e-mail address my invoice was sent too) and the order number EXACTLY as it is in the e-mail. I have tried entering it manually as well as copying and pasting it. Yet, your website returns this error: No such purchase, please try again.
I know you are an indie developer but purchasing your games really should be easier than downloading a cracked version. Also your website has been extremely slow this entire day. Maybe the two are related.
I am sorry for the negative nature of my first post on your forums, however I did not register my account for this sole reason so hopefully I will return with a more pleasant demeanor very soon
