If any one could give me some direction it would be much appreciated. So i have been working on a project for some time and I have been stuck on this for about a year too a break and now and coming back to it so I figured its about time i knock it out so im a little foggy on what I was doing then. Getting back into VS :/.

Due to a memory leak while using webbrowser over time my pc starts to lag to the point where the application crashes. So to fix that i was forces to dispose the webbrowser to free up memory then create and re-parent it to SplitContainer10.Panel2 and start fresh with new details to browse. But as you can see from the image i am getting a error and Im not sure what it means exactly or how to fix it.

Any help or direction how to fix this is much appreciated.
