Questions/subscriptions

Hello,

I own Adobe Creative Suite 5.5 Master Collection. I am taking a class in Fireworks 6 so I need access to that version.

1. Can I get a 30 trial, then pay a monthly subscription fee for just Fireworks after my trial ends so I can finish my class?

2. How much does that cost... just for a Fireworks subscription?

3. Also, can I do this without messing up my current install? My class will be done November 20th.

Any steps or links that someone could provide would be helpful.

I have looked all over the website, all I see is info on Creative Cloud.

Thank you.
