R help - Mar 2013 - xzfile() cannot open the connection, lzma encoder error 5.

Dear guangchuang,
I was stopped by the following error when using Package: clusterProfiler on R
2.15.3 on windows 7.
Error in xzfile(file, “wb”, compression = 9) : Cannot open the connection
In addition: warning message:
  cannot initialize lzma encoder, error 5
The too functions: Gff2GeneTable() and buildGOmap() are not working because of
this error.

Could you please let me know how to fix these error.
 [source of the package:
http://bioconductor.org/packages/2.11/bioc/html/clusterProfiler.html]
 
Here are what I typed in R:
