Hazel 3.2.7 wont let me licence

Hi All, New to this forum.
I have been running x7 versions of Hazel 4.1 for some time with no problems, however I have a Mac that I can't upgrade from Lion so I found you had some older versions, I downloaded 3.2.7 which works fine, but I can't seem to License it, I have a spare license from a 5 user batch I just bought for v4.1 but it won't accept this, so I went back to the store to purchase another license for 3.2.7 but I believe the license sold is only for 4.1.
My question is, if you only sell the license for v4.1 should that work for v3.2.7 and if so why would the 5 user license I have already bought not work? Hope you can help me out here.
By the way the contact form on the support area isn't working, been trying for a couple of days now.
