And I haven't yet downloaded an earlier version due to people complaining that the uploaded files don't work...
There is a safe, free and working version of Pokemon Type Wild 4.3 around. I'm not allowed to post a direct link (according to forum rules), but if you type 'download pokemon type wild 4.3' into Google, there should be a result near the top that leads to answers.com - the answer to the question on there should have a related link which takes you to a safe download place.
It's a bit long winded but it works.
Hope this helps!
:D
