need help Importing from IPB 3.3.0 to XenForo 1.1.2

I have just purchased my copy of xenforo and am having issues importing from IPB to XenForo

I did use the IPB 3.2 import tool but got the below error when I selected "import user groups" and entered the correct details in the "Configure User Group Import" screen, I assume thats because I used the 3.2 importer when I am on 3.3.0 ?

any help would be fantastic ?
