When I first setup this iPrint appliance last summer it was working fine and I was able to add drivers to the driver store without any problem. Recently I needed to add a new driver and I am now getting the error "java.lang.NullPointerException" any time I try to add a driver. This comes up right after selecting the driver from the system or from the hdd. I have run out of ideas trying to search log files etc looking for a hint of what the problem is. Any ideas about where to look would be appreciated.
