HOWTO
Here's a complete guide on how to hack your uxtheme.dll file. NOTE1: You don't have to do this if you have already installed an older version than the 4.0
NOTE2: If you still want to use StyleXP Email TGT, tell them you were using their beta software, and that it expired. They've always maintained that all betas will be free, so they should give you a registration key to fix the problem. Either that or just download the newest beta. They've also promised to always release a new beta before the old one expires. Either way - you should not have to pay a cent and hopefully you can get it fixed quickly.

1) Backup UxTheme.dll to UxTheme.000
2) Don't blame me if you screw this up, these directions are as is in their somewhat correctness and I am not responsible for the government raid that will happen if you conduct this change. I have tested this and it works for me and the 500 other folks who have used this method. Do not put tinfoil in the microwave.
This is very simple to do and amuonts to changes to 17 values and takes less than five minutes to do. This also assumes you don't have StylesXP installed on your system and that you are working with the original UxTheme.dll
3) Open UxTheme.000 in a hex editor, not resource hacker.
4) Replace the following 4 sections in the hex code with the values I provide. You will need to use the
search function in the editor to find the exact address within the file to perform each edit
Adress: 0x00009C27
Original: 02
New Value: 00
Address: 0x0000B624 --> 0x0000B629
Original: 0F 8C 80 00 00 00
New Value: 90 90 90 90 90 90
Adress: 0x0000B6BB --> 0x0000B6C2
Original: 81 EC 80 00 00 00 56 57
New Value: 33 F6 8B C6 C9 C2 08 00
Address: 0x0000B71E --> 0x0000B71F
Original: 7C 38
New Value: 90 90
5) Check your changes, make sure you did not use the letter O in place of zero. SAVE
6) Reboot to safe mode (press F8 before the bootup-screen appears and choose boot to safe-mode), rename UxTheme.dll to UxTheme.bak ... and rename UxTheme.000 to UxTheme.dll
