Hello, I am using a software called PCPhone(from Phonewala) to call US numbers, Yesterday I upgraded my yahoo messenger and did a voice chat with my friend. After that the PCPhone software refuses to connect. What may be the probable problem? I have uninstalled both the software and installed only PCPhone and still the problem persists. Moreover, the website www.phonewala.com is no longer accessible from my PC while it is from any other computer. All the other web sites are working normally. I don't have a clue as to what is blocking both the website and the desktop application ? Any help will be greatly appreciated. Thanks in advance.
