Need help fixing 102 error on wii...

Hey guys, Sorry to bother you with this.
I recently got a physical copy of PSO 1&2 on GC and wanted to start playing online but I just can't seem to get it working.

I have a soft modded wii with nintendont. Emulated the BBA, used an emulated memory card, typed in all relevant information noted in the GC connections guide including the most recent (I think) IP adress, use the serial number and access key from my manual for (easy remembering) and registered them on this sit, entered them in the game.

But each time I am getting a 102 error and I just don't know what to do at this point...

Does anyone know what could be the issue?
