Could you please try to open your solution, delete your old references and then add the new references to our assemblies.
As I see the error below I think that it is very possible that you have some properties serialized so if you have manually changed something in your form's designer please remove it and then try to reopen it again. Warning 1 The designer cannot process the code at line 126:
this.radTabStrip.TabScrollButtonsPosition = Telerik.WinControls.UI.TabScrollButtonsPosition.RightBottom;
The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again. C:\Documents and Settings\hchattaway.PINPOINT\My Documents\Visual Studio 2005\Projects\ErrorLog\ErrorLog\ImportErrors.Designer.cs 127 0
I hope this helps.
All the best,
the Telerik team
