I have discovered that the same error also occurs when i go to "tools > Tex
information" and do a
rescan. The problem occurs when there is no spaces in the directory too. and
I'm not running from
a usb stick.
No, currently the path is 'E:/WSSCI/bibtex/wssci.bst'. This is a folder on a
USB drive.
Then please update you MiKteX-installation using MiKTeX's update wizard program (available in via
Windows' start menu, requires an open internet connection). Run the update program twice if necessary.
Does it then work?
