Umlaut import, again

[E.Kaplan]

I am sorry to have to return to this issue, since I thought I had a 
solution. 
It turns out that this solution (\usepackage[latin1]{inputenc} ) works 
ONLY on my home machine (Windows XP sp3-miktex 2.7), but not on my 2 
office machines (Windows XP-sp3 miktex 2.7 and kubuntu 8.10 with livetex).
On the office machines I still am getting the error: Unknown parameter 
name {a}ssle because I have an a with an umlaut.
It seems like a small problem, but it will make my life MUCH easier if I 
knew how to import Latex files with umlauts in them.

Thanks,
EK
