NIS2009>>>NIS2010 Question(s)

Just a few questions...

 

I have NIS 2009 and it is activated with 99 days left.

 

1. Is there any problem with buying NIS2010 and installing it? Will it work without me having to uninstall NIS2009 first?

2. Will I loose the 99 days I have left or will they be added to my NIS2010 install...ie: 365+99 days for the new expiration date.

3. Are there any issues with NIS2010 on Win XP Pro SP3?

 

I am asking this as OD has this 3 user pack for FAR Tomorrow!
