Augen customer service is pretty shabby, but take a look at post #16 of this thread:

An official update is allegedly planned for release on August 30th which is supposed to address the accelerometer screw-up from the previous update and the SD card issues. Of course, Augen could issue a statement to that effect in the "News" section of their CS site, but they seem to prefer keeping customers in the dark.
