it is possible, that's for sure
Please do not get me wrong, I never implied that it was impossible, just very difficult or expensive, given the obvious solution that I suggested. Any, all and every security system can be broken, unless it is a destructive one.

Can you remember anything about your password?...........how many characters? was it a word/mix of words or just random characters, mixed case, numbers and symbols?

IMHO unless you have some "intelligence agency strength" kit a strong password will take weeks to bruteforce........which is how it should be?............if I could tell you how to do it then anyone else could do it, and your system would not be secure............the lock that keeps out the burglar will also keep you out, or it is not worth having?

I find it odd that your administrator is away without someone to deputise who knows what to do and has the admin password? For "odd" read bloody stupid and incompetent!

If you want the e-mails, do you know who they are from?..........get them to resend...........was anyone else on the distribution list?, ask them to forward you a copy.

My answer remains the same: it is probably impossible, within a reasonable timeframe,
that is.

Cheers

EDIT: A word of advice............get rid of that demo software..........some people just might not understand
