Failed to import key from file. (wodFtpDLX / wodFtpDLX.NET)

Self Solve:

In reviewing the file and comparing to others that were successful, noted that the files that failed were saved in the ppk version 3 format:

PuTTY-User-Key-File-3: ssh-rsa
Encryption: aes256-cbc

and those that succeeded were in the older format:

PuTTY-User-Key-File-2: ssh-rsa
Encryption: aes256-cbc

Saved the keys in the older format and loading the key file succeeded. Guessing that this component was upgraded for that newer format at some point
