[BioC] One run and dead

[DMITRY GRIGORYEV]

Hi!
I am running Bioconductor on WindowsXP and can do just one job at a time.  When I've submitted another job my machine got memory problem (I have 1G of RAM though).  I am exiting Bioconductor and open it again.  Memory problem is fixed by this (is there hanging pointers somewhere?) but affy library is screwed.
This what I have:

Error in mlistMetaName(f) : No way to associate a generic function with an object of class "NULL"
Error in library(affy) : .First.lib failed

The only way I can fix it is to reinstall whole package again.

Is there Uninstall function for Bioconductor, which will not uninstall R?
How to fix described problem?

How much memory should I have to run 33 U133 chips at once?

Thank you
