[BioC] Lumi: LumiT vst transform error

[Sarah Allen]

Hello, I am having a problem performing vst normalisation on my data.  
I get the following error message that I can't make head or tail of:

 > lumi.T <- lumiT(lumi.B)
Perform vst transformation ...
2011-02-25 11:07:29 , processing array  1
Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) :
   0 (non-NA) cases

I have searched the archives and found that people have asked the same  
question before and the advice has been to update their Bioconductor  
package. All my packages are up to date, I have made sure that all my  
values are positive using lumiB "forcePositive", my boxplots all look  
fine (there is nothing intrinsically weird about my data) ... I am  
stumped.

Can anyone help?

Many thanks, Sarah Allen
