Start SecondLife problem

just created account d/l client installed and after start it shows "Detecting hardware..." and that pops the following error:

"Second Life is unable access file that it needs.

It can be because you somehow have multiple copies running, or your system incorrectly thinks a file is open. if this message persists, restart your computer and try again. If it continues to persist you may need to completely uninstall Second Life and reinstall it."

I tried to restart comp and reinstall the client. Nothing helps.
Here is some quites from dxdiag file of my comh specs if this might help:

"Second Life is unable access file that it needs " usually comes if you have a character in your login name SL dont like " øæåòàèìù " ect, if you have a odd character in user , SL wont find the file as its kinda dumb, only way to fix that right now is to make a new user, or move the document folder (wich isnt as easy)

SL installs some files on
C:\Documents and Settings\"username"\Application Data\SecondLife

SL need to be able to find it, wich it cant with odd character , dumb i know.
