MIB File could not be parsed

I'm getting errors when trying to load the Traps on a MIB File using SNMP Trap Processors - Load from Mibs.
and I'm getting the errors from the logs below. Could you please check the file to see if there are characters that Opmanager can't handle? The file does not contain underscores.

Thanks,

Marcos
