I just bought an Acer AOD257 which has (Chinese traditional character) WIN 7
(start) installed.
But MikTeX seems to have problem for downloading packages.
I have never successfully compiled a XeLaTeX file so far.
Whenever the program need to download a package, it stopped at unpacking the
just hang over there.
However, if I killed the process, and restart compiling, it seems the package
already installed well.
All packages loaded this way....
However when the process goes to loading eu1lmr.fs
it just stopped there. Even if I killed the process and restart.
Part of the log is shown below:

("C:\Program Files\MiKTeX 2.9\tex\latex\base\fontenc.sty"
Package: fontenc 2005/09/27 v1.99g Standard LaTeX package

("C:\Program Files\MiKTeX 2.9\tex\latex\euenc\eu1enc.def"
File: eu1enc.def 2010/05/27 v0.1h Experimental Unicode font encodings
LaTeX Font Info: Try loading font information for EU1+lmr on input line 100.

("C:\Program Files\MiKTeX 2.9\tex\latex\euenc\eu1lmr.fd"
File: eu1lmr.fd 2009/10/30 v1.6 Font defs for Latin Modern


The same latex file runs well on my PC which has XP system.
Could anyone tell me what is wrong? Thanks.
