Standalone Atmega328p using Arduino as ISP

I am uploading a sketch to a standalone Atmega328p with an Arduino Uno R3 as ISP. The standalone chip does not have a bootloader. I uploaded a sketch and it was succesful, now when I try to upload another sketch I get this error:

avrdude: verification error, first mismatch at byte 0x0002
0x44 != 0x5c
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

Any help would be greatly appreciated.

Is that what you get when attempt to upload via ISP again?

Yes Ive uploaded one sketch via ISP now when I try to upload another sketch via ISP I get that error.

thanks for the response
