"Specified method is not supported." error in attempting to open certain older .ark files

[jbradshaw77]

Hello,

I've been downloading and playing PvE on old save files, downloaded from the repository over on savetheark.com. Some of the saves seem to work well with Larkator, but many do not for some reason. Sometimes when attempting to load in an old save, I get the error, "Specified method is not supported."

If it helps, an example of a save that does work is in the "Deprecated Legacy" server list, arkfiles.com/pc/2018-02-10/nitradouswest42.ragnarok8.zip

However, in the "Conquest" server list, "EU-PVP-Official-Ragnarok-Conquest14" does not work, and I get the error.

Any ideas on how I can get around this issue?

Thanks so much - great program by the way!
