Help please I really don't know what to do.

Welcome . . . but, your first forum post has a need for more questions than answers . . .
How were you hacked ? Are you running windows, or mac OS ? Can you not launch Sonar at all ?
More info please.

Hacked????
It sounds like you think anyone would know what that means, but no one does. 
 
You should be able to run it on an Intel based Mac under Bootcamp, but you would still need to install Windows.

Someone found there way into my network and locked me out of lots of my programs including lots of important files pertaining to sonar including sonar itself.
I was running it on Windows 7 x64 and I'm not totally locked out of sonar but can't change any settings. I also own a Mac which is my reason for asking

Are you in a position to reformat your drive and reinstall everything?
 
Are all of your important files backed up (as they should be)?

I tried to start the process of re formatting but it wanted to use an exemplar from existing software I didn't carry on.

Unfortunately not as I hadn't got that far yet.

Excuse my ignorance, but what is "an exemplar from existing software"?

look at the bright side...even the strongest of viruses wont lock you out of your bios.

A "clean" install will be required.  That means reformatting the hard drive and then installing Windows (and all other software).
 
 

Take the infected PC off line, including the LAN connection as well. No point in letting the hack keep doing whatever it might be doing across the network, your computer may be spewing malware, viruses or spam every where. While you're at it, make sure you have locked the intruder out of your LAN completely - this is vital.

Then doing anything download Malwarebytes free version and see if you can run it.

Ideally do this by downloading it on to another computer (a Mac will do even though it can't run the application) and put it on a Windows file format CD/DVD so whatever is running on your PC can't over-write it or infect the disk it's on.

Some low-level root-kit malware takes over the boot drive's boot sector and sometimes can survive a simple disk format, it can also infect any writable media, disk, stick etc. that is connected to the PC and lurk there waiting for a chance to re-infect everything.

Handling this kind of thing is really beyond what this forum can do, you really need a specialist site that can go into detail about what's going on. Malwarebytes forum might be a good place to start.

If you have a clean Windows installation disk that can be used as the boot media, and the drives formated there as part of the installation routine. Do not use a "quick format", a full format is far more likely to delete an infected boot sector. Be aware that drives other than the boot drive may also be infected.

I say again, dealing with the kind of infection you seem to be describing requires some experienced, specialist advice.
