1. Relicensing issue: I was confused.
some articles say that it is only free for the first 3 years?
other articles say that it is free for 4 renewals per year..which is which?
The WF licence is valid for 3 years. During those 3 years, you can reinstall WF over and over and over again on the same computer as many times as you want. Because of the way WF generates its licence number, you'll need to get a new licence number every time you reinstall WF. To prevent abuse by pirates, WF will only give you new licences a few times (four per year?) before the site require that you send it an e-mail to verbally tell them you're not a pirate.
2. Modes of Payment:
what are the modes of payment? (considering i am based in the philippines)
I have no idea. I used a credit card both times I bought a licence. I'm sure if you can't use normal methods, Yves (the creator of WF) will accept other methods of payment.
3. How long would it take to get my license?
For me, it was within 24 hours both times.
