Intel 4004 emulator problems?

Hi everyone,

Apologies if this has been reported recently; please feel free to delete this post if it's a duplicate.

I am encountering technical issues with the Intel 4004 tasks (specifically "Mul Two"):

Submission Error: Clicking "Submit" results in "failure :(" even with a logically correct solution. If the solution field is empty, it just says "fail".

Emulator Error: On the Intel 4004 Emulator Wiki page, I consistently receive: "Error happened during request to server!" when trying to run code.

Thanks for your help!
