I had the same issue at about the same time as the others. I did all the newest update of windows and then still had the issue, so I solved it by changing the "Log on as" part of the X10 Device Network Service (X10nets.exe) in services.
1. Press ctrl-alt-delete, find and select "x10nets.exe" in the process tab, and click the "end process" button. If you can't find it, skip this step. You can then close the "Windows task manager" window.
2. Go to start RUN
3.Type "services.msc" in the run dialog and hit enter
4. Find the x10 device network service, (should be all the way to the bottom in alphabetical order.)
5. Right click on the "x10 device network service" and click properties.
6. in the "log on tab" click the "This account" selection bullet and click browse.
7. in the select user box, click advanced.
8. Click the find now button without doing anything else in the advanced "select user" window that just opened.
9. Select Administrator in the name (RDN) column of the list and click OK EDIT** You can use any user you want**
10. Click Ok once more in the other windows where administrator appeared in the "Enter the object name to select" box
EDIT****
Thanks
Wister for this input, I added it here so that "the fix" is complete here!. There is a thing to know about the password, here is the quoted post from Wister.
Quote " The "trick" to this had to do with the password noted in step 11 of the original "fix" posting. I did not have passwords for any of the accounts on the system, since it was always used by trusted users. I went back and created a password for my account and used that account and password in steps 9 through 11. After that all way well.
I hope this helps clarify things for others who may have tried the "fix" without success."

11. Put a password and confirm it in the password and confirm password box.
12. click ok .
13. back in the servies window, right click the x10 device network service service in the list and click start. The service status should change to started quickly and the log on as column should read .\administrator.
14. Start Active home pro. it should start fine, mine did.
Try it out and tell me if it works for you, I know it worked for me!
