guys please help me,, Im using DevComponents office ribbon for the inteface of my application, every thing seems ok, but sometimes my IDE suddenly crashes until I get this error message when I open References section in project property:

An error occurred trying to load the page. Exception has been thrown by the target of an invocation.

also allot of errors regarding my fonts are being generated like

Warning 1   Font 'Arial' does not support style 'Bold'. C:\Documents and Settings\Admin\My Documents\Visual Studio2008\Projects\Electronic_Examination\Electronic_Examination\ViewAccount.Designer.vb   40  0

in every form
even if I reinstall my visual studio 2008 it still can't fix the problem.
