If your calender is not set correctly it can do this.
Could maybe be the daylight saving time which happened today?
Thanks for the speedy reply Daniel, unfortunately all looks to be normal on that front, and in fact NZ Daylight Savings hasn't kicked in yet (it's in April). Perhaps that conflict could be the cause? Although, then I'd expect the same error to occur on my personal computer.
Now that would be interesting, see if it goes away in a few hours.
No cigar so far.
At home my trial still has the correct trial period info. Well, in the meantime I have put forth a business case to buy Flex 3 at work (:P), though perhaps someone can advise on whether I am in fact able to purchase Flash Builder 4 in it's beta state and when it is shipped, I'll be able to upgrade to that (for no extra cost?)?
I just got into the data binding stuff and that stretched my thinking a bit, so if I have to write code in Flex 3, to do what FB4 has done for me already... well, not keen really .
