[BioC] Gviz UcscTrack error

[Anna Sawicka [guest]]

Dear All,
Gviz refuses to generate a UcscTrack. The code below worked in the middle of December:

genetrack=UcscTrack(track="RefSeq Genes", table="refGene",
                    trackType="GeneRegionTrack",chromosome="chr5", genome="mm9",
                    rstart="exonStarts", rends="exonEnds", gene="name", symbol="name2",
                    transcript="name", strand="strand", name="RefSeq Genes", feature="name2",
                    showId=T, from=30334169, to=30349988, fill = "green")

But now it generates the following error:

Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  : 
  line 1 did not have 2 elements

R as well as Bioconductor version is up-to-date. Does anyone know what the problem might be?
Thanks a lot!
Ania
