main': C:\Documents and Settings\()()()\Desktop\arduino-1.0\hardware\arduino\cores\arduino/main.cpp:11: undefined reference to setup'
any help would be great
UM... are you sure your program has a setup() function in it. This sounds like a source code issue, NOT a hardware/upload issue. Otherwise, post your source or no one will can probably help you!
You need to post your code; we're not psychic.
(though I can guess pretty well)
