问题：
使用 VXDIAG VCX SE BENZ 诊断工具大约三次后，它提示 VCI 许可证已过期，无法启动 09/2024 Xentry。我尝试使用桌面上的“VCI Recovery”工具进行更新，但仍然无效。尝试在 VX Manager 中更新许可证，它提示更新许可证失败，错误 4001。
解决方案：
VX Manager 网络显示“离线”，表示计算机未连接到互联网。
您必须有网络连接才能更新许可证。
更新许可证并重试。

Better buy from another retail website where one can get the products even cheaper with better return policies and most of all much better support. On the VXDIAG website there is no custumer support at all on how to use it. They do not provide any software-link and leave there customers completely alone. If one wants to return an item they charge 15% restocking fee. Pathetic customer service even though they reply quickly.

Regarding the SE for Benz device you purchased, according to the product description (https://vxdiag.com/products/vxdiag-vcx-se-for-mercedes-benz) and our user manual (https://vxdiag.com/pages/vxdiag-device-user-manual), we clearly stated that Mercedes diagnostic software is not provided, as we do not have reliable resources for Mercedes software.

This tool works very well and has many years and models available. I used the support and the technician was very helpful and kindly. I really recommend this tool to everyone that needs it to solve every car problem. Thanks so much for the team and particularly to Shiny!
I had a few problems with software at first, but this is not unusual with any software; there are so many variations in peoples computer hardware and software set-ups that can affect a programme.
The VXDIAG tech support team found the cause though. They are very polite and professional. Email assistance cured my Windows 10 installation for GDS2 and for my Windows 7 installation (for Tech2Win), they offered me remote assistance and they found the cause very quickly.
I have now tested my VCX-FD on my 2007 GMC vehicle and the Tech2Win software now works flawlessly with this J2534 device.
It's well worth getting through a few minor software issues to get a J2534 device that does everything that a much more expensive tool can do and will keep working with newer cars in the future.
I will be trying online SPS programming in the near future, using an ACDelco TDS subscription, and it's good to know that the VCX-FD specifications show that the VCX-FD is more powerful than most comparative tools and will easily allow programming modules much faster than the old Tech2 and many others.
Out of all the sellers Ive worked with, this one left a really friendly impression, and working with them has been a pleasure. The product quality is excellent.
