[nissanwarrior69]

there is no other opsu running at all

[yugecin]

Try changing the port in the .cfg file

[nissanwarrior69]

I did and it still giving me a error but not a port error

[Swimgiant]

I am getting this issue with the port as well even if I change the port

[nissanwarrior69]

Ok then

[yugecin]

If it still happens, edit the .opsu.cfg and set:
NoSingleInstance = true

[nissanwarrior69]

Ok
