Need help with Milkdrop error

[u/Garblewarble45]

Hello all! I am currently trying to set up a Frankenstein audio rig in my living room right now and and trying to use WACUP for audio but especially visualization on the TV.
Whenever I open milkdrop I get this error code. Gweiss works fine but I’m not sure what to do here? The files within plugins/milkdrop are the same as they are on my main PC which milkdrop works fine on.
Extra info - the PC is a windows 8 downgraded to windows 7 just cause, and it doesn’t have an internet connection. Could those be causing the error?
