Yes I know this problem has occurred, and has already been solved on these forums ""

I've had the same problem for a year everytime I attempt to start the campaign.
"This save file could not be loaded because the file has been corrupted or is an invalid save file."

I've tried reinstalling GOOH, I've tried verifying game cache, I've tried deleting my SRIV saves, I've tried using the onfoot radio mod (By Minimaul and turning "load_sriv_character" to "False"

I've tried so much, so I'm just curious if there's anything else I could try
