error 2036 & 2035 DeBug mode FlashBuilder

[roialgavish]

Hello,

When I am trying to run an app in the debug mode in flash builder I am getting the following error:

In chrome: error 2035 without any massage.
In IE: error 2036 with the following massage:
Load Never Completed. URL: http://127.0.0.1/flexviewers/bin-debug/widgets/WidgetContainer/WidgetContainerWidget.swf

When I run the the release version it works, I have read the relevant threads and didn�??t find the answer for that.
Can someone help?

I will admit that I am new in the programming side if the GIS, and trying to teach myself.
Thank you all,
Roi algavish.
