XF 1.5 Error Importing from Xenforo to Xenforo at Import Nodes

I am trying to import from an old version of Xenforo (XenForo 1.2.9) into a more current version of Xenforo (XenForo 1.5.20 Beta 2). However, when I get to the "Import Nodes" part, it pulls up the following error:

Server Error

How can this problem be fixed so that I can proceed with the import? Thank you!
