Lightbulb Error E4491 and E4423

I find solution and extremely disappointed in GM and ACDELCO customers support.

The problem turned primitive.

Solution:
Before you begin, make sure that you PC have following requirements:
1) Turned off antivirus
2) Turned of Firewall
3) And last and most important! Check the latest version of Java on www.Java.com

I have Java 6 Update 21. After update to version 7 update 9 ECM was successfully programmed.

Make sure java is at the latest update on your pc and that you don't have any firewalls on in your antivirus. I've never had any problems on gm going on 100+ reflashes. I do however have a dealer login instead of of using acdelco site.

2108 model year is still 89 years off and you might have a nine minute wait between sentences to get tech support's response from Mars

Usually you need an older java.The tool box software tells you to turn off firewalss and allow acdelco.com specifically.Why would you use a j box for that if you have a tech 2.
