It may be unrelated to your problem, but sometimes when I hit tab, the pipboy does not come up. If I hit escape to bring up the menu, hit escape again to get out of the menu, then the pipboy works fine. You might try that. Hope it helps.

I made a post earlier before seeing this one, requesting the same thing. It seems like a small thing, but I bet it would add a lot to the immersion of being the wolf. I know nothing about scripting, but if no one else picks up the torch on this one, I may try & learn the hard way.

It did not work for me. Same message pops up. Hmmm.... Are you setting the esp you wish to modify as the active file when loading up the plugin?

Got it figured out on my end.. Darkworld420, are you using windows vista, or windows 7. If so, instead of double clicking the Construction set icon to run it, try right clicking it & select "Run as administrator". I have windows 7, and using this method to launch the Construction Set allowed me to save the chenges I made to the esp. Hope that helps.

I have the exact same problem. Oblivion is not running when I am using the const. set. I've never had that problem before, but with my recent hard drive failure, I've had to purchase a new hard drive, and formated it with Windows 7. I lost all of my old oblivion stuff, so I've re-installed, started a new game, re downloaded mods, construction set, and now all of a sudden I have the same message about being in use, or a master File, when I try to modify and save an existing esp. I tried deactivating the esp in mod manager and then opening construction set to make changes, but that makes no difference either.
