DEXSeq error - Error in lf[[1]] : subscript out of bounds

[mbk0asis]

Hi,

I was going to try DEXSeq for the splicing analysis, but I got stuck at the beginning.
I got 'subscript out of bounds' errors when tried 'DEXSeqDataSetFromHTSeq'. The error seems to tell me that sample or column numbers were not matching with something else.
I don't really understand it. Please, somebody tell me what did I do wrong?

library("DEXSeq")

sampleTable <- data.frame(
    rownames = c( "IVF1","IVF2","IVF3",
                  "cSCNT1","cSCNT2","cSCNT3","cSCNT4",
                  "fSCNT1","fSCNT2","fSCNT3","fSCNT4"),
    countFiles = c( "~/00-NGS/RNAseq/bov/Old_Pico/Ensembl/DEXseq/IVF1.counts",
                   "~/00-NGS/RNAseq/bov/Old_Pico/Ensembl/DEXseq/IVF2.counts",
