Error when starting OpenOffice 2.2 in Mac PC

I was starting OpenOffice 2.2 on my Mac when I randomly I got this error, see below.
This was weird because I was able to use it just yesterday.
I tried reinstalling but the same error happened.
I tried searching the web but to no avail of finding any possible solution.
Any advice on what to do next?
Hope you can help ASAP.
Thanks in advance.
