eWin Expansion & GBA Loader 2in1 won't work with sdhc

im wondering if theres a patch that will allow me to use the eWin Expansion & GBA Loader 2in1 with sdhc cards as when i run it with my 2 gig chip it works 100% but when i run it with my 4 gig chip it shows a white screen when i patch it for my nintendo opera browser.
it does however work 100% with gba game patching im wondering if theres a fix or something i need to do as im useing the dstt card with 2 and 4 gig chips

edit: also if anyone knows of the ewin website or latest firmwire that might fix this i currentally use 1.06 gba ewin loader firmwire this would help greatly
