VS2010 crashes intermittently with System.ArgumentException: value does not fall within expected range

The following error appears in Activity Monitor Log.xml file

System.ArgumentException: The value is not in the expected range. at Microsoft.VisualStudio.Web.CSS.ICSSLineTokenizer.TokenizeLine (ICSSTokenFactory factory, Int32 lLine) at Microsoft.VisualStudio.Web.CSS.Implementation.CSSColorizer.Microsoft.VisualStudio.Text.Classification.IClassifier.GetClassificationSpp VisualStudio.Text.Classification.Implementation.ClassifierTagger.d_0.MoveNext () in Microsoft.VisualStudio.Text.Tagging.Implementation.TagAggregator`1.d_16.MoveNext ()

In the source column, it says "Editor or Editor Extension"

This does not happen every time, but on average once a day. If I reboot it everything is fine. This happens in any part of the code, be it a css file or cs or aspx file. Can anyone please help?

As a consequence, I got the Resharper error below in the Activity Monitor XML file.

Unable to load one or more of the requested types. Get the LoaderExceptions property for more information. C: \ Program Files \ JetBrains \ ReSharper \ v7.0 \ Bin \ JetBrains.Platform.ReSharper.VisualStudio.v11.dll

and

Guys, I'm not an expert programmer, just a beginner and newbie at StackOverFlow. So please forgive me if I am posting to the wrong place or website. If anyone can be kind enough to state this. \ Thanks.
