Hi Experts!
This is the second time this is happening to me.
I have a valid Flash Builder 4 license. I had installed flash builder plugin over Helios 2 months ago. It worked fine until today. But now I am not able to open mxml or .as files.
This is the error I get.
java.lang.NullPointerException

Here's what led to this problem. This is my office laptop and the license was purchased by the company.
1. I had to change my SSO password as it was about to expire. We use Lotus notes (built on eclipse) to do this.
2. I opened eclipse and tried to open an mxml file. And this is what I get.
About 2 months ago, I had exact same problem. I had to use a new laptop to start working again.
Please help me.
