You'll have to wait till someone makes an update I'm afraid.

is there away to fix my dsi and play my acekard games without updating

I don't think you can downgrade the DSi's firmware

There is a Acekard2i fix for the DSi 1.4 firmware.
But you need a DS Lite or a DSi without the 1.4 firmware to run the update. (Because you have to run it from the Acekard menu)You can find the update here:
