Hey Guys!
Same problem here with update 2.61. I tried updating in safe mode, tried using different USB ports, even a different PC but nothing helped. However I was able to roll back to 1.32 (that was the latest update I had on the POD HD500X before I tried installing v2.61) with no problems at all. I don't really know what should I do next as I would like to buy the new HD metal and bass packs, but with v1.32 I wouldn't be able to use them..
