Before you contact Skype Support, try to uninstall Skype altogether, download an installation file from their website, and install it anew. That usually helps if an update corrupted installation. Also when you get your Skype working, go to Tools-Options and change your update settings, so that Skype will notify you when there is an update, but you will decide whether you want to download and install the update or not.
I guess contacting the Skype Support is the best solution in this case, rather than applying the hit and trial method.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
