You can however I just tried and your access is fine for both in Mozilla and IE.
You own a Photopost license and a Reviewpost license and the email is the same on both
You can get your own license details by going to the members area and entering the email address on both when you fail authentication
Photopost members area
Reviewpost members area
Note the members areas are different you do not put your reviewpost members access into photopost area.
I just went in and sent the members access info to your email for Photopost
