Please read this page if you experience difficulties with your TimeSlice serial number.

• General information
• Macintosh specific

Serial number does not work.

• If you recently purchased a TimeSlice serial number, it will work with the latest TimeSlice release available from the TimeSlice web page. However, you must copy to the clipboard the serial number from your email order receipt, and then paste it to the TimeSlice registration window. DO NOT copy any extra characters to the clipboard such as extra space characters or carriage return characters. DO NOT attempt to type the serial number, you must copy and paste it.
• Delete (or archive and delete) all older copies of the TimeSlice application you have on your hard disks.
• Older versions of TimeSlice may require a new serial number. For example, if you have a TimeSlice 2.2 or earlier serial number, you will need to upgrade to a new serial number for TimeSlice 2.5 and greater.  TimeSlice 3.3 and above for Mac may require a new serial number (see the Macintosh Specific section below).
  

You get a message stating the serial number is already in use

• It could be someone on your local network is already using the same serial number. If so, you need to use another serial number.
• If no one is using that serial number, restart your computer.

Macintosh specific

Serial number does not work (continued from above).

Starting with TimeSlice 3.3, we had to modify the TimeSlice algorithm for computing serial numbers.  This was due to Apple deprecating some functions calls for the new Intel chips.  If you serial number works for TimeSlice 3, but not for version 3.3 or above, please contact Modesitt Software for a new serial number.

It's unusual, but the TimeSlice preference file could be corrupted.  Try the steps below if your serial number still doesn't work.

1. Quit TimeSlice if it's running.
2. For TimeSlice 2, locate and delete the file "TimeSlice Prefs" which is located in your Preferences folder. 
   
3. For TimeSlice 3, locate and delete the "com.modesittsoftware.TimeSlice.plist" located in your Preferences folder.
4. Copy the serial number from your email.  Do not include extraneous characters such as carriage returns or space characters.
5. Start TimeSlice, and paste the serial number to the registration window.

Where do I enter the serial number?

How do I remove the serial number I'm now using?

For TimeSlice 2, select "Unregister" from the TimeSlice File menu.

For TimeSlice 3, select Unregister TimeSlice from the TimeSlice menu.
