I2C Help

hi there
i have a card reader and i am suppose to talk to it using i2c
but i have no idea how to do that
i am using fed pic c ide and i a have been trying to simulate talking to
an i2c device using the external devices that the pic c ide provides
but it does not work.
it give me messages like "clock too short" and if i increase the time
too some numbers appear on the device which is not the data i want to
write

any help?
if any body has talked to a card reader before using i2c i would be
very grateful if things could be explained to me
