I had the same issues as others with regards to the barcode... Tried to get in, wouldn't let me, so I went and joined the massive queue at the TO. The LFC help team only realised there was a problem when we all turned up unable to get in, and then it was discovered that the barcodes weren't working so we had to re-download the tickets. Once downloaded again, no issues and straight in.
Great day in the end though and voice is still fucked!
