Issues when uploading DumpInfo from MFRC522 onto Arduino Mega 2560

Using Arduino Installation & Troubleshooting
#1

Hey, so I'm fairly new to the whole Arduino scene and recently bought a brand new Arduino Mega 2560.
When I try uploading DumpInfo from MFRC522 I get the error:

avrdude: verification error, first mismatch at byte 0x0000
0x14 != 0x33
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

I'm using the most recent version of the arduino software (1.8.5) and I am on the operating system Windows 10.

Thank you for any help!

I'm guessing this isn't specific to the DumpInfo sketch and will occur no matter which sketch you try to load. Is that correct?

#3

Yeah that's right, after trying to upload other sketches it seems that it happens for all of them
