Hey 618707845285,
Nicely done checking the REST Super details through both the Super Lookup tool and REST’s own website. To get around the "This fund can no longer receive contributions using Pay Superannuation. Please edit the fund from the Superannuation Fund List window and select a valid Fund Name for it." error, the best move is to create a fresh REST Super fund in your list. Enter the ABN and USI/SPIN, hit OK, then link this new fund to your employee. Once that’s all done, you'd be set to run super payments again.
Cheers,
Doreen
