License file no longer valid

After updating my PC to Windows XP SP3 Maple no longer runs. A box with the message: "

Invalid or missing license file

License server does not support this feature

Feature: Maple 11

License path: c:\Program Files\Maple 11\License\license.dat

FLEXlm error:-18,147

appears and Maple does not start. Maple worked fine before SP3 update.

Does anybody have the same problem? Any idea about how to fix this?.

It would appear that the SP3 upgrade altered the license file and required the reintalling of Maple (I upgraded to Maple 12. Something to think about when upgrading Xp to SP3

A very alarming and bizarre notion, that it would alter the file.  Do you have any evidence that this was the case?
If it was, a cure should be simply to replace the altered license file with a backup copy (which is a good thing to have in any case).  But I recently upgraded XP to SP3, and had no problems with Maple 11 or 12.
