Default DESeq2 SummarizedExperiment0 Error


So it's been a while since I used DESeq - I was trying to get DESeq2 working and I run into an error just attempting to run the example code from the vignette, running:

directory <- system.file("extdata", package="pasilla", mustWork=TRUE)
sampleFiles <- grep("treated",list.files(directory),value=TRUE)
sampleCondition <- sub("(.*treated).*","\\1",sampleFiles)
sampleTable <- data.frame(sampleName = sampleFiles,
fileName = sampleFiles,
condition = sampleCondition)
ddsHTSeq <- DESeqDataSetFromHTSeqCount(sampleTable = sampleTable,
directory = directory,
design= ~ condition)
Gives me the following error:

Error in initialize(value, ...) :
cannot use object of class “SummarizedExperiment0” in new(): class “DESeqDataSet” does not extend that class
