lambda statement incorrectly highlighted in red

Hi guys

I'm looking for an option to fix ReSharper so that my lambda statements will not be flagged as wrong hence leaving my class with a red square in the upper right corner...

ReSharper version: 4.5.1288.2, VS2008 SP1

code:

    for (var filer = _importfolder.GetFiles(Filter).OrderByDescending(fi => fi.LastWriteTime).ToList();
         filer.Count > 0;
         filer = _importfolder.GetFiles(Filter).OrderByDescending(fi => fi.LastWriteTime).ToList())
    {
