I'm no expert but I've seen this problem of produce sticking on other pages of this forum. The general advice is to look at what's on your timeline at 30%. It might be something PD can't process, like a faulty transition, a photo that needs reducing in size or a corrupt file. That bit might need re-editing or cutting. It might be easier to test a re-edit by producing straight to documents - I don't create discs.
It won't help if your PC is slowing due to disc and registry clogging or fragmentation. 'Ccleaner' is a good free PC cleaner.
'Auslogics' is a free defragmenter.
As for upgrading to PD10 (there is no PD12), it seems to need a high power PC. I tried the PD10 trial (which is not a full feature version) and found it more unstable and a bit slower on my PC - 32 bit, AMD 5000+ dual core,
Radeon 4600 graphics, 4 gig ram, Vista HP. This is not high spec and it doesn't look like yours is, unless you have a more
powerful CPU and 64 bit. You could try the trial. I didn't find it much different for the basic editing I do.
