I am currently running the VERY same version of WD on WIN 7 Ultimate on a MORE than capable machine also. I am using a Davis serial DataLogger. I do not see the issues your speaking. More than a few of us are running this combo without the issues you speak of so that would lead a person to question it being on your end. Go back to what works. Easiest fix right?
But than again, With the PISS POOR attitude you exhibit over the last several posts it's no wonder you had ANYBODY offer up a solution.
What is it with some people
Must be the winter "Pissies" setting in.
Very hypocritical last bit of your post there.

I don't know what it is with your people, i'm pretty good at debugging problems myself. I just don't know how many more times i can tell you, that it's simply a problem with the latest WD, obviously not just on Windows 7 as someone else has pointed out the same problem on another operating system.
And being both of us have reverted back to the old version with out any problems suggest something has changed in the later releases. If you don't have a problem with your WD, then stay out of threads that don't concern you. I've been more than polite in my posts, but people just don't seem to get it.
No one has even bothered to explain why knowing my location makes a difference to WD freezing? Quite comical really haha.
And Windy, if you don't wish to fix problems with WD, that's your problem. I've given your more than enough information on the matter, and i think you, and a few others on here that have posted HAVE been rude. You've failed to read the posts carefully, because you insist on asking the same questions that have no relevance to the problem. I'm seriously wondering why i ever bothered to purchase this software with the attitude of the developers on here. I've read countless posts over the months that go to prove it.
I'm not doubting your ability, you've done a fab job with WD, but this forum is anything but fab, and this thread goes to prove it.
All the information was given wayyyyyyy back in post 6 of this thread.
Also, i might add that i haven't been sending ANY rude emails to anyone, and that posting that you have had rude emails is poor practice, you deal with the matter with the person, not plaster it on this forum for others to read. It gives the wrong impression.
