I can reproduce this - very odd. I'll investigate a fix it.  In the
meanwhile, install the aroma.* 2.8.0 versions via CRAN, e.g.

install.packages("aroma.core", repos="@CRAN@")
install.packages("aroma.affymetrix", repos="@CRAN@")

(Add repos="@CRAN@" to make sure not to install from other repositories.)

Thanks for the report,

Henrik
