[BioC] DiffBind error loading dba.count

[Paolo Kunderfranco]

Dear All,
I am facing some problems with RGUI loading dba.count with my dataset,

> setwd("C:/Documents and Settings/pkunderfranco/Documenti/Data/ChIP-seq Roberto/Analisi_PK/DiffBind/H3K27me3/")

> library("DiffBind")

> test= dba(sampleSheet='database.csv')
ES_H3K27 ES H3K27 1  1 raw
CMN_H3K27 CMN H3K27 1  1 raw
CMA_H3K27 CMA H3K27 1  1 raw

> test=dba.count(test)
AppName: rgui.exe	 AppVer: 2.150.58871.0	 ModName: diffbind.dll
ModVer: 0.0.0.0	 Offset: 00003be1

Did anyone faced the same problem? which are the memory requirements
to run DiffBind?
Thanks,
Paolo
