I haven't seen a post on this site yet, so I thought I would mention it.
Solid Edge ST6 Maintneance Pack 3 was Released 11-25-2013.
As usual, you should find Solid Edge ST6 files at:
Have tried the link, but how do you actually get to the download part, as to be honest
it all seems a bit of a maze to find it,
The link @jinglis provided takes you [once logged in] directly to the ST6 section of the download directory....so click on, Solid Edge > choose either 32bit or 64bit [relative to the SE install, not OS] > MP03 [or any other available]....and it should start downloading.

FYI - If you use SEEC and Structure Editor, test ST6 MP3 fully. We found issues and had to abort our upgrade last Friday.
