Do I HAVE to upgrade to 4.0?
 

I currently own 3.8 and recently received an email saying mine expires on Feb 24th 2010. I logged in and went to the purchasing section and the only options I have are to upgrade to 4.0 for $175 or $250 for 4.0 suite. What is going to happen on the 26th if I do nothing? I'm not leasing vB so why does it expire? There is also an option there for "no upgrade" which is what it is defaulted to.
