algo loading error

hello,

I downloaded an algo indicator and it runs well for a year, but recently it can't be load.

check the log file print: 

| Error |  Crashed in Initialize with ArgumentOutOfRangeException: Index and length must refer to a location within the string. Parameter name: length

could some dev help me ?
