I just downloaded the project to check as it it is kind of old, however I do not see these errors and it runs fine. Make sure you copied all the files in the /Libraries and the /Templates folders from the BANano zip file to your Additional Libraries folder, not the default Libraries folder of B4J.
EDIT: also check in both libraries folders if you do not have some old copy of the BANano.xml/jar file. These are B4J errors you get (I think, I should see the full log to be sure) typical to missing or a wrong version of a library.
