Well I know there are many issues with people, including myself, who used PC Connect. Freezes, PC Connect locking up, computer locking. I let windows update my drivers (just picked each one and went through the process), went into power management and disabled all 'sleep' functions of the USB hubs. For some this works, many many others it still does not work. It did not work for me (Windows 10-64). At least my drivers are updated, was surprised how many were not.
The simple solution is to use VIS Reader
http://www.valleyinfosys.com/visreader.html. It is free for basic reporting (WU, PWS, WB) and cost a small subscription to post to CWOP, CSV data and much more. Designed specifically for Acurite USB connect stations.
It is the same reader you see when you open up PC Connect, except they keep updating it, and have excellent customer support in their forums. It also uses PC Mode 4. I heard Acurite displays have a firmware issue with USB Mode 3 that has caused some hiccups. If you end up checking it out and subbing, mention my forum name and I think you'll get a bonus. Since using that I went from consistent crashes to absolutely zero now over a month.
Good luck!
