Problem: There was an error reading from the dongle data area.

If the error occurs every time the dongle is accessed: This suggests that the dongle memory has become corrupted. Re-write the data area by re-programming the dongle with DinkeyAdd or by using a secure update code with DinkeyChange. The secure update code must modify the whole data area.

If the error occurs intermittently: Ensure that your software is protected with the latest version of the SDK. Check that the computer's motherboard and/or USB adapter drivers are up-to-date. Also check the dongle and USB port for signs of damage or a loose connection.

This error could also occur due to a bug in versions of DinkeyChange earlier than 5.6.1 (the data area is not corrupt and does not need to be re-written). To resolve this problem, ensure you are using the latest version of the SDK.
