GPS Data Logger Software - BT747

IMPORTANT: JAVA 7 (1.7.0_51) now requires that BT747 is signed with a TRUSTED CERTIFICATE.
You can also lower the security level of JAVA 7 to 'medium'.

BT747 is signed since version 2.1 with a certificate.

To do so, I bought a trusted certificate (provided by a trusted authority) for about $300 (valid a few years).  Received it on Jan. 17, 2014.

Thank you (!) to the user that already contributed to help cover the certificate cost.
