Premiere Pro CS4 Crashes every time I try to open it

Question

Every time I open premiere pro wheather its a HD project or SD project, or even one that I worked on before in it, it decides that it needs to crash, how can I fix this?

Answer 1

As Curt says, it is below the minimum. Those minimum specs. are to allow one to install the program, and are not even a guarantee that the program will run, let alone edit. [If Adobe asked me, I'd set realistic "min. specs." so that one could at least edit simple SD Projects.]
Now, when it worked once upon a time, but not now, Curt is correct - something has changed. Were I troubleshooting, the first thing that I would check would be the I/O sub-system, i.e. the HDD's. It is likely that you have one HDD, and that it has filled up over time. It is likely that it is now too full to allow PrPro to even start up. Were I doing the investigations, the first thing that I'd look at is the defragmented free space on the HDD. For PrPro, my minimum would be ~ 100GB, AFTER the Page File (statically managed and set at boo-up) has been written. The listed min. is probably around 30GB, but that allows no breathing room. If your Page File (Windows Virtual Memory) is set to be dynamically managed by Windows, then it is what is likely filling to overflowing and shutting things down.
Personally, I'd be looking into a new computer, but if you are doing SD only, and would like to troubleshoot things, to try and get back to using PrPro, as before, take a look at this ARTICLE, to get an idea of all the info that will be needed here.
After you look into my speculation on HDD space, and satisfy that requirement, take a look at this ARTICLE, on getting the most possible out of your computer, especially for an editing session.
If you do decide to invest in a more robust computer, please see Harm Millaard's great articles in the Hardware sub-forum. He discusses, in great detail, every aspect of a computer for video editing. They are better than one would ever get from talking to a sales rep at Dell, HP, Gateway, et al.
Good luck, and please let us know how you'd like to proceed.
