Error (4) when loading presets

[ProjectAD]

I just jumped into the ship today since I believe this is one of the best synths out there. And I found I have many presets for it already from many libraries i have stored. Thing is, when I try to load the presets in Sylenth1 I would get a Error(4) telling me to make sure it is a valid sylenth1 preset. Any help? are these presets too outdated? Or Im I doing something wrong?

Hi, error 4 means that the preset/bank file is from another VST plugin, not Sylenth1.
