Hi, I just reinstalled TxDb.Hsapiens.UCSC.hg19.knownGene and it does not function. When I load the package, the TxDb object looks fine, but applying any function to it fails.  For example genes() gives character(0) and seqlevels() gives an empty GRanges object:



> library(TxDb.Hsapiens.UCSC.hg19.knownGene)
> txdb = TxDb.Hsapiens.UCSC.hg19.knownGene # abbreviate
> genes(txdb)
GRanges object with 0 ranges and 1 metadata column:
   seqnames    ranges strand |     gene_id
      <Rle> <IRanges>  <Rle> | <character>
  seqinfo: no sequences
> seqlevels(txdb)
> library(TxDb.Hsapiens.UCSC.hg19.knownGene)
> txdb = TxDb.Hsapiens.UCSC.hg19.knownGene
> txdb

We don't support old versions of Bioconductor, so the first thing to do is upgrade to R-3.4.1 and the current version of Bioconductor. That will probably fix things, but let us know if you are still having problems.
