FB 3 Eclipse plugin activation

[Guest]

Hello,

I have problem with FB3 plugin for Eclipse. I have professional license for it and it worked fine. But last week a window with "Trial period expiration" text appeared. I filled valid professional serial number and this window disappeared. But later each attempt to modify .mxml or .as file causes this "trial expiration" windows display. I tried to remove license.properties and .com.zerog.registry.xml files, but it doesn't work. Now I can't modify/create any mxml and as files. Please help me.

It seems like flex builder plugin displays, that serial number is valid, but it doesn't remember it (it ignores valid serial number). Please help asap.
