When I try to upload a MIB file I'm getting the next message:

Error parsing MIB:FORTI-DDOS-MIB.mib
Exception while loading MIB:Could not parse the file C:/MANAGE~1/OPMANA~1/./mibs/FORTI-DDOS-MIB.mib. The error occured at the line no: 97 ,column: 17. The identifier should not start or end with number or special character.

I've attached the file. Can anyone help me??

Thanks.
