Paul,
i forwarded your issue to the software compiler team. They said that for some legal reason, the ARM compiler from TI has to be updated from CCS, but they are checking again.
I have the single download version with me, but i can not send it to you even in private link.
Is there any possibility that you can use a guess network in your company to install newer version of compiler?
As far as the breakpoint, there are only around 6 supported.
I will forward this to our compiler support team to see if they can give any suggestion, but please try to download 5.1 from your network somehow first.
