Arduino upload to Mega256 fails

I got the SainSmart Mega2560 LCD Keypad Shield Sarter Kit and want to upload the demo program for this LCD keypad. The IDE runs under Win7 x64 and the driver is correctly installed, I think.

I only get error messages

avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer
avrdude: stk500v2_command(): failed miserably to execute command 0x10
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.

How can I check, if the connection really exists? Are there any know issues?

It is very strange problem, I encountered this problem when I attempted to connect IO expansion shield with Arduino 2560. I have tried many things but it didn't work. After many attempts I removed IO expansion shield from Arduino and then upload, It was worked. There is no clue why it can't upload when IO expansion shield is plugged. So this is a workaround solution but it is working. It is enough for me now.

--- FIXED --- The problem has been fixed by checking all wiring on RS-485 network. GND and Termination wiring was missing after set these wiring properly the problem was fixed automatically. If you have this problem, I suggest that checking wiring once again.

It seems, that many users have the same problem. My solution was now, that I removed the LCD Panel and the upload worked.
