You will need to upgrade to at least NFA 9.1.3 to be compatible with any version of CAPC.
The most recent current version is actually NFA 9.2, with 9.2.1 due out soon. However you cannot upgrade directly from 9.0 to 9.2, you must first be at 9.0.161, then you can upgrade to NFA 9.1.3, from there if you are on Windows 2008 R2 servers you can complete the upgrade to NFA 9.2.
You can find the NFA 9.1.3 Upgrade Guide below:
