The e504sp.tsp file is part of Eumex 504PC USB Telephony Service Provider from Deutsche Telekom AG.  A tsp file has nothing to do with teaspoons and everything to do with communications.  The tsp file sets up the parameters of an internet phone service, allowing you to use your telephone through the internet.  This particular file is part of a USB driver for a VOIP (Voice Over Internet Protocol) device.  It can also be part of a USB ISDN modem.  An error with this file may affect your internet phone service or your internet access itself.

The most likely cause of an error listing this file is in the registry.  The Windows registry keeps track of all the pieces of programs and drivers on your machine.  If it loses track of a piece, or a piece gets moved, the registry will generate an error when you attempt to use that program.  To fix the error, you need to clean up your registry.  ZookaWare PC Cleaner is a registry cleaner with a 100% guarantee.  We will fix all the registry errors on your computer, and allow you to get back to more important matters.
