Error avrdude: stk500_getsync(): not in sync: resp=0x00 in versions above 00023

Dear Sirs,

I have one problem to download sketchs in Arduino Duemilanove with ATmega328.

I have board Duemilanove with ATmega328, I use Windows7 x64.

When I use version 00023 or below everything is working properly, but when I try to use version 1.0.X always I have same error:

avrdude: stk500_getsync(): not in sync: resp=0x00

I check the board type Duemilanove with ATmega328, I change configuration in Windows 7 of COM port, from 9 to 2 to test if with lower COM is working.

I change also bauds of the Com port, I upgrade the drivers with last one from FTDI web site. But nothing work.

I remove USB drivers, disconnect and connect again, and update with different USB drivers.

And Download with version 00023 is working always but with versions 1.0.1, 1.0.5 and 1.5.4 never work.

When start to try to download, first L13 blink, after RX led blink, but TX led seems to not blink. After few seconds program show error avrdude: stk500_getsync(): not in sync: resp=0x00

If you can help me to solve it it will be nice. I use at the moment arduino-0023 version, but I like to use the newest versions with new boards.
