Assistance on Sipek SoftPhone

I need to work with sipekSoftphone. I compiled correctly [login to view URL] and [login to view URL] (I'm working on Windows, with Visual C# 2005 Express Edition) The application function correctly in debug, but after publishing it and install [login to view URL], app crash and close after first call. I need too tips for howto implement the [login to view URL](IVoipProxy proxy) event. In conclusion:I need contact someone that know couple C# + sipek; the idea is chat with skype o MSN; if necessary, candidates will be able to install sources code on own PC, for generating same workspace in tha I'm working. I cannot calculate the time necessary to resolve my trouble so, I need your budget FOR 1 HOUR of consulence.
