Unable to open VuGen in 12.02 version

Hi,

I'm unable to open VuGen, when i open the following error messages are popping up.

1. Error loading Addln c:\program files(x86)\HP\Loadrunner\Addlns\ICSharpcode.sharpdevelop.addin: ",hexadecimal value 0x02, is an invalid character. Line 208, position 31.

2. Search & Replace has not been loaded because it requires SharpDevelop.

3. Critical error( cannot use ExceptionDialog) - this  displays a big message.

Additional details:

OS: Windows 8.1

Able to open Controller and Analysis.

Thanks in advance.
