When importing a v2c file, I get Error Code 43 HASP_DEVICE_ERR "Input/Output error occurred in secure storage area of Sentinel SL&nbs;key OR a USB error occurred when communicating with a Sentinel HL key"; what can I do?


Please try to install the latest driver or the latest program version first. The link for the driver can be found below.

Reload the v2c file after the installation. If it does not work, please send us authorization.txt, which you can create by clicking Help → Authorization → Diagnostics.
