Problems after beta un-install

Setup: WIN XP Home SP3, NVidia GForce 8600 GTS, Intel Dual Core.
I had 4.4 and 4.4.3 running without problmes, but after installing 4.4.4, TLB frequently froze the PC. I uninstalled 4.4.4 and tried re-installing 4.4.3 (TLB settings showed 4.4.4, however), so I completely uninstalled TLB and re-installed 4.4. Now I get errors when creating new menues ('could not be created'), no Icons can be put in the TLB bar, even the WIN Quick start menu can not be shown ('could not be created') even after completely removing TLB.
So it seems I am a bit lost now...
(Sorry for the short error messages, but I have a DE/de region installation, so I do not know the english message texts.)

I guess the Quick Launch folder is deleted. This is strange because the uninstaller don't delete this folder hock:

Just create the folder Quick Launch, on the path:
%appdata%\Microsoft\Internet Explorer

Also please can you test this version? I guess this version fix the froze computer bug.

Thanks for your quick response, that's really great!

Your installer does not, but I use an uninstall software, this one deleted the folder.

Just create the folder Quick Launch, on the path:
%appdata%\Microsoft\Internet Explorer

Done, and Win quick launch was ok again.

Also please can you test this version? I guess this version fix the froze computer bug.

Also done, incl. restore of its' content; no crashes so far.
Thanks for your help.
