own game and have played before, sudden .dll error?

[jimboslice69]

Hello, sorry to bother, but I have played for the past year or so. I owned all games prior and they have worked without issue on plutonium. But, as of late, it claims to not have the right .dll file. I have verified all the games files and uninstalled and reinstalled both plutonium and all full game files. any help is appreciated
