AEM not working with GeoIP2 databasereader

I'm working on implementing an IP based redirection script. This involves using Maxmind GeoIP2 database to find out the location of the user. The problem I'm having is that there's a specific line that's causing AEM to break. If I comment out the line, the page displays as it should, if I uncomment it out I get the following errors:
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: Cannot find a a file corresponding to class za.co.npw.utils.NavHelper_v2 in the repository.

Below is the code that I'm using. The databasereader line in black causes the exception error. Any ideas on what could be wrong?
