Configuration Error:1 Adobe Flash Builder 4.7

Hello,

I'm using Adobe Flash Builder 4.7(64 Bit). Instalation went well and Flash Builder worked just fine,  but after restarting my computer and opening Flash builder again -  popup appeared with Configuration Error: 1. I thought that this was one time only, so I uninstalled and reinstalled the product. But this Error is still appearing. So now I'm uninstalling and reinstalling my product every time this happens - sometimes it works, sometimes not. How can I solve this problem?

Thank you in advance!
