Hi all,
is anybody familiar with the Math + Card for the 48GX ?
Well I have one and I inserted it and it said 'Invalid Card' ... or something similar.
I tried to turn the calculator ON and OFF some times but it always gave the same error. Then I tried to use the 'PINIT' function, and it stopped the error message ... but now, when I go to the Library, there is nothing on the card. :(
Have I destroyed the memory contents of the card?
