Extension licenses for CCSv5.1

I'm using CCSv5.1 for OMAP-L137 debugging with an XDS510.

My initial evaluation license + 90 day (?) extension period is coming to an end and the license tools tells me I can't have a further extension. I can only get quotes for CCSv4 licenses from vendors here in the UK, so it seems I'm out of luck to keep running with 5.1 until the official release in October and vendors add it to their stock.

Is there any way to get hold of a license key for 5.1 now? An extension key valid until official release will do, but I can raise a PO if I need to buy one.

Thanks,

Nick.
