On July 12, 2012, the Maple license server that hosts Maple 11, 12, and 13 will be retired. This means that all network installations of Maple 11, 12, and 13 will cease to function at that time. Note that standalone installations for Maple 11, 12, and 13 will not be affected. If you are still using network Maple 11, 12, or 13, please begin using either the network installation of Maple 14, or any other standalone version. Current versions of Maple can be downloaded from http://software.caltech.edu. If you have any questions about this, please contact IMSS Software Licensing (software@caltech.edu.)
