I dont know how this has happend because the program did work in the begining but just one day i started to get this error msg every time i try to og into options on stuffplug, i dont have this problem with any other plugins, its only this one

Anyone know why? and can i fix this in a way?

Edit: added a pic of the error, and if i remember right i got a error msg about some microsfot visual c+++ but i'am not sure, but it was something with microsoft visual c+++ to i think.
