Asset store issues.

I have unity version: 4.2.0.f4. When I initially start up unity the asset store works. I am usually able to download and import 1 item. After that I get a white screen and nothing loads. If I exit unity and load it back up the asset store works initially and then stops working. On the web it works fine however if I want to import items into unity the asset store in the application does not work.

Computer:
Windows 7 x64 (latest updates)

Is there a current issue with the store or is there something I can do to resolve this issue?

Maybe you should contact Unity’s support. Normally after downloading new content from the store we are asked to import the content in the project. We don’t have the issue you are talking about.

Just maybe, you should look for that window behind another window. Or maybe, you’re computer is lagging while getting the new asset.

Anyway, if you feel like it, you always try to reinstall Unity. If the issue is still there you can consider getting support from Unity team.
