I change skins on a regular basis. If you are a W/Bs user dont upgrade to verion 6.1. I did via stardock central, and it wont let you apply any skins. Why stardock do this is beyond me.

6.1 works great for most folks.  I'd suggest you install it again and post yoru system info (in a new post) so we can see what is wrong and get it fixed.

Sorry but i do not intend to install again as i have tried 3 times already.

There's no shame in asking for help. 6.1 has significant improvements over 6.0. No bugs that I've seen. Runs very well on my low-spec rig w/Vista Home Basic.Why not put the terrific resources available here to work for you.They won't give up 'til your fixed. Good Luck!

Thanks wizard1956 i will give it another go.

Is it a good idea to uninstall W/Bs 6.00, before installing the latest 6.1 version ???? thank you.

It shouldn't be necessary.
Are you updating through SDC or Impulse?

Zubaz i am updating through SDC.

Downloaded again via SDC, still will not let me change skins. system info below.

When i try to change skins , it trys but fails to change until i reboot and the skin has changed to the one i attempted to change. Very strange, it looks like i will be going back to ver 6.0. frustrating. !!!!!!

Just hold on a bit so support can take a look at what you have going on.

Will it let you re-apply the normal windowsUI without a reboot,or does it hang then also?What skins have you tried?If you want,post a little more of your system specs, and steps you're taking.I'm sure that will help.The mods may move this thread over to a better spot,where more may see it. Hang in there.

You may even want to start a new post,like Zubaz suggested.{edit} didn't see Zubaz's reply til after I replied,sorry.

Sounds like you are hitting some sort of caching issue. If you didn't restart right after the update then you can get this error with your settings. Normally I have a file you can target to delete and let the software restart but not as much with WB.

So I hate to say this but try uninstalling, restart, redownload/reinstall, then restart again before running the software. Let me know if that does the trick for you. Normally I like to sound more intelligent in my answers but I think simple is going to work best here.

Seabass i have tried all what you have suggested, all to no avail. I have gone back to ver 6.0. as i have uninstalled and installed to many times i Will close this matter, and wait for another update to W/Bs, then try again. Thanks for the help and suggestions from everyone.
