I have the same problem this isnt a perfect fix but it will do

first you need to go to c:\program files\wincustomize\logon studio

minimize that windows you will need it later

next your gona need to open that file to get to the files inside so your gona have to get 7zip

The download to this program can be found here http://www.7-zip.org/download.html

Download and install

afterthat find one of thoes files you couldnt load filename example.logonxp

right click and click open with click browse go to c:\program files\7-zip and find the file 7zFM select it and click ok or whatever

make shure its not checked to allways open with this program then click ok and you should see a buntch of files bitamps and stuf

minimize that then maximize the window from before right click and create a new folder with aney name you like

open it then pull up 7-zip and copy all thoes files from there inside the folder you made

startup logon studio and the name of the folder you made will appear basicly your doing what logon stufio would have done it it had opened the file good luck i hope i helped

I am having a problem with the latest LogonStudio, it also will not change the boot screen, (I have not tried the safe mode administrator though)...

I am also having problems with bootskin, i change the picture and it sets it as Active, but still loads the preinstalled Timewarp OSWARP logo even though it states after startup that the default xinxp bootsrceen is Active, completely denying the fact that I changed it originally, I will try this in safe mode as well, hopefully if I put a password in admin it will run as and save me a lot of problems that I didn't used to have prior to system destruc recovery, Home Edition problems with access denied.. why can't it run like it did, I am guessing it is all because of sp3 install update stalling out and not finishing cleaning up.

Another problem: I´m running xp with tuneup utilities, winblinds, winstep extreme and descscapes. Whenever I try to load a new logon screen with logon studio it sets tuneup utilities to  standart logon, but loads winseven logon screen. I cannot find the application, that is responsible for this and the fact, that logonstudio is unable to set its screen as default.

problem solved by using logonxp instead!
