Microsoft has issued instructions on how to fix its Zune device after mass crashes of the media players.

The problems emerged earlier this week when users began to report that players were freezing and could not be accessed. The issue was limited to the 30GB Zune 30 model manufactured in 2006.

The issue was soon traced to a bug in the player's internal calendar components. Because 2008 was a leap year, the players were unable to adjust the calendar when switching into 2009 and crashed on new year's eve.

The bug brought back memories of the Y2K fiasco, when many feared that the inability of computers to readjust clocks for the new millennium would lead to worldwide system failures.

Fortunately for Microsoft and Zune owners, the problem is now easily fixed. As of noon GMT on 1 January 2009, the player will reset its calendar and operate normally.

The company is advising users who have not already done so to leave the frozen players activated until the battery drains and the player shuts off. The Zune can then be connected to a PC or AC power adapter when it will reset and operate normally.

Users are also being advised to re-synch their Zune with a PC in order to fix any digital rights management compatibility issues caused by the crash and reset.
