I'm not sure what happened. Last week I run windows update on my computer. I have .net 2.0 & VS 2005 installed. Now anytime, I open my c# project w/ View Designer, I've got an error:

One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.

Invalid class string (Exception from HRESULT: 0x800401F3 (CO_E_CLASSSTRING))

It was fine before and now it's error where it never error before. Same project is fine when open on other computer.

I search on google.com & microsoft.com but I didn't found any case that same as mine.

I already re-install VS2005, .net 2.0 a few time but it still didn't work. If anybody could give me some advice, please let me know. I'll appreciate that.
