I think this might have started at the last ICS update but I'm not positive. Every download, including app updates, fails with an error code 101. After messing around for a while, it appears that Google Play doesn't recognize my device any longer. I did all of my checking on my TF101 last night, including using the stock browser to log directly into Google Play, where i checked my devices and it said I didn't have any. Now today on my work PC I logged in and it shows my TF101. Can't get on wifi here so can't check to see if things are working, but I'm guessing not. This is a huge impact issue to me of course so any advice is very much appreciated.
