There are problems encountered on the Phil-IRI. Most of the schools were not able to validate their entries due to problems occurred like "#ref" appeared on the data encoded and re-encoding will give an error message and will not accept the data.
I have tested the application and it works normally. The buttons allowed me to load the necessary data to start the application. However, I have used a sample file from a certain website and it worked normally. There was no error or issue with the file and the application. I recommend downloading a new version of the application then double check the data you want to load because you will receive errors if the file doesn't correspond with the standards.
