What you describe might be something that has been encountered by  
many users of tlmgr: when it updates itself it removes itself! The  
GUI is using some Perl scripts. When one of them is deleted during  
the update procedure then it also has to fail, at least at some  
moment when this script is called.

It seems to be recommended to first check if and which updates are  
available. If the packages texlive.infra and bin-texlive are listed,  
then it's recommended to either install them at once (tlmgr will be  
replaced, TeX Live binaries will be replaced, causing also the re- 
creation of FMT files, MAP files, ...) or leave them out till the  
end. In this latter case it might happen that tlmgr gains some new  
functionality and you might need to run it again to see whether new  
updates are available.

For UNIX PCs a recovery script for tlmgr exists that re-installs the  
updated tlmgr when it is run or executed. For MS Windows a similiar  
means *has* to exist when tlmgr is not meant as a failure by itself.  
So, when tlmgr makes itself unusable by an update, you should not  
delete and reinstall TeX Live 2008 but just fetch this recovery  
script and execute it.

Visit http://www.tug.org/texlive/tlmgr.html (I don't know whether  
it's too early or the fact that I installed the latest security  
update from Apple and my Mac OS X does not work completely, but this  
site hurts in my eyes!). There you'll see a paragraph "Disaster  
recovery" – and it points to http://mirror.ctan.org/systems/texlive/ 
tlnet/2008/update-tlmgr-latest.exe. http://ctan.org/tex-archive/ 
CTAN.sites lists mirrors.
