Unable to sign up in Skype

I have created an account in Skype and I am using it for months but suddenly I am not able to access my system. I have created my account using my yahoo account but still I am not able to access. The problem still persists. Is my system causing the problem and not allowing accessing my account or should I need to create a new account or is there any other way to access my old account. Please help!

See there may be several problems regarding system which is not allowing you to access your Skype and yahoo account. There may be a connection problem. Just recheck the connection. If the problem still persists, you can also try one more solution i.e. just uncheck the ports box. Ports box is basically used to harden your system disallowing your firewall to work. This may solve your problem.

As you know that firewall is designed to permit or deny network transmissions based upon a set of rules. Thus it may allow some connections or disallow some. So there is possibility that your firewall might be blocking your connection with Skype. So, check your firewall settings first, go to control panel, open windows firewall and verify whether it is blocking Skype access, and if it is, just add Skype to the exception list.

Also, there can be number of network connections provided to you. You can access all of them but still your ISP has set a password for those connections and given a password for your network which you can access. By accessing wrong network you may not be allowed to access the internet. Just your check your network connection and you may also take your ISP’s help for it. This may help you to access your Skype and yahoo mail.

If you have moved from one operating system to another such as Windows 7, there are several problems that this operating system has regarding Skype. Downloading a new version of Skype and installing may not work. If you are using Windows 7, then perform these steps: Right click on the Skype icon, go to compatibility tab, and choose the OS you were using before and try to log in. I hope this may solve your problem.
