Query: equus 3130,and equus 3100 Diagnostic code scanner

I purchased the equus 3130 automotive code scanner first, only to find out, that it is to complicated to operate.After I downloaded the info to the PC, to get the required information,I found out that you have to pay for a report.When I called customer service, it was a 4 on a scale of 10.After I returned the unit, I bought the lower priced model 3100, here I found out that I cannot download my information to the PC at all.Called Customer support, I was told it is my PC.It wont let me download any info.I checked with Computer Experts,Smart Computing,and had several answers.I cheched all out, with no avail.Calling customer service again, and they have no answer.So they leave you to hold the bag by yourself.Something has changed in the Softwa, but they denying it.For customers which are on the market for such a device, be aware!!!!!
