However Sock Monkey is right, and so am I. Let go or stick within your limitations.
> When you buy something at that price, you expect it to work for years.
Not for 8 years, and even Windows XP itself is no longer supported by Microsoft. And no it's not worth $4000, Sock Monkeys estimate is far more accurate. So your PC cost $500 a year, you had pretty good value.
And what you've already experienced/written seems reason enough as well.
Let go or continue the pain (or use older version of Sonar as Sock Monkey suggests, but if you do prepare to experience more pain).
Cheers....
