I got cat et on eBay already installed on Dell laptop with windows 7. Had all the programs for trucks. Insite Allison etc. it just stopped working. Said it was for future date. My truck is an 07 379. Do any of you computer whizzes know how to fix this? The date on computer wasn’t accurate but I never checked anything. Was supposed to last several hundred years. I rarely use it. But now that I need it it won’t work. Tried to find the guy bought it from but it was 4 t years ago n eBay don’t go back that far. Tried to get them to send info to no avail. Any help would be much appreciated
