That's interesting. You are using a compiler version that has not released yet! The latest one is 4.101.

The CCS linker no longer produces an initial type 4 intel hex record at the start of the hex file. This may be a problem for your programmer. If this is the case you can prepend the hex file with a type 4 record that sets the high order address to 0x0000

There may be an option to force generation of this record but if there is, I don't know it.
