There has been a login glitch with Skype for few users yesterday. The problem was due to a specific xml file, “shared. xml”.

Manual instructions like quitting the app and deleting the file were given to Window (7, XP, and Vista) users. Skypes Peter Parkes promised an update for Mac, and advises the Linux users to follow the manual instructions.

A new version for Windows is now available for download. The corruption has not affected users using Skype on their mobile phones or TV. This glitch reminds of the experience of last December that paralyzed service for the video- and voice-chatting worldwide.

Although the problem was fixed in time allowing service online for Christmas holiday, yet questions were raised about the VolP service’s reliability. The decision of not renewing an agreement that allows open-source telephony system Asterisk to be integrated with the service using software is more about a change in strategy, rather than the company closing the door third party integration.

Steve Blood said via e-mail that Skype’s decision not to renew the agreement is a sign it going forward will “open up” to the external community more through Skype Connect.
