//RegMon//

Here are stored the reg infos :HKEY_CURRENT_USER\Software\Acon AS\Acoustica\2.0\RegisterInfo\Company
HKEY_CURRENT_USER\Software\Acon AS\Acoustica\2.0\RegisterInfo\Key
HKEY_CURRENT_USER\Software\Acon AS\Acoustica\2.0\RegisterInfo\Name***********************************************

In the dead listing, U can find strings :
UNREGISTERED messages =>
"The evaluation period has expired."
"The key does not match license "REGISTERED messages =>
"Your license is registered. Thank "
"The key does not match license " can be found at addresses 4472CE & 446FAB
to go here, U must go via the jump 44729C & 446F6B at offset 0x4689C & 0x4656BU can see that if the jump doesn't occur, U go in the REGISTERED part of the code with the
"Your license is registered. Thank " string.opcode: 7425 je xxxxxxx can be replaced by 7525 (jne xxxxxx) or 9090 (nop nop)
Then the REGISTERED nag screen appears whatever U enter in the name/# dialog box...
***********************************************
//Pushing the date 2 months later//
***********************************************
It enables to use the soft after 30 days....
After 30 days, the nag screen "The evaluation period has expired." appears.
U click on "OK" and the register box appears...
then whatever U enter, U'll be able to use Acoustica, in comparison with the original file
which is automatically closed & the help opened.The first day, i export registry HKEY_CURRENT_USER\Software\Acon AS\Acoustica\2.0
I advance clock 5 days later, and repeat the last action.
I compare the 2 reg files and see they are the same.
U can see too that, U open Acoustica the 1st day & the 5th day...only 2day of use...
The soft don't count the days number of use, but the difference between install date & today date.
So I conclude there is no information saved to keep the number of use.
The only one can only be the date of installation.
***********************************************
//Number of use//

Another interesting reg key :
HKEY_CURRENT_USER\Software\Acon AS\Acoustica\2.0\Reverb => 0x1bf6107 (29319431)Eternal Bliss say to add 0x80 => the result is to obtain the expiration nag screen...
If this string is way to write the date of installation, this date was put back (the today date is still the same).
The limit value is 1bf6130
1bf612f=>still work (+ 0x28)
1bf6130=>expired version (+ 0x29)Try to decrease it now...
1bf6000 give 1 day of use
1bf5f00 give 2 days of use1bf5e00 give 4 days of use
1bf5d00 give 5 days of use
1bf5c00 give 6 days of use
1bf5b00 give 7 days of use1bf5a00 give 9 days of use
I will not to try to find the exact limit but a day must be equal to a number between 0 and 0x100....
