Hi,
thanks for your suggestions.
Regarding my "problem". I am using Windows 7 64b Proffesional. I use Opera as my only web broswer. I have disabled IE in Control Panel\Programs and funtctions\Turn on or turn off function of Windows system. When I install GC2U old version of Impulse is installed also. When i try to run it, it crashes and requires reinstall. Once I reinstall to fully new version it works.
Question is if it can be influenced by IE which I disabled?
I will ask on mail you have suggested kryo and try the download link you provided also.
Thanks again.
