I have been using bd since 2008. I upgraded to BDTS2011 a few weeks ago. Since then, my computer is extremely sluggish and has grey outs when loading. I tried to run the support tool application, but after 30 min, no progress was made by the tool and so I closed the application. I tried to use it 2 times. My computer info: Vista 64bit, 2GHz, 4 GBRAM. What other info can I provide?
