The XML in the license file indicates that it is valid until May 29, 2013 (see below). Please note that I removed the serial number and key information. I tried to compile a program and it states that the license file is invalid. This is preventing me from completing my work. Please contact me ASAP. Many thanks in advance.

This is not a non-redistributable license
I suspect you or somebody else might have changed your license file, because if its expiry date is May 29, 2013, then there should not be any problem and it will not give your invalid license error.
You may get help from Aspose.Purchase team by posting into their forum, you may try to get a new copy of your license file too.:
If you still find the issue by using the new copy of your exiting license, let us know here. We might require your license file to check it if it is changed or not.
Also, check the document on how to set the license file:
