I seem to get the above error after I have uploaded a program to the chip twice and then if I restart my computer I can only upload a program twice again before I get the error again but I don't want to have to continuously restart it after uploading a program twice. I'm using a micro magician v2 and my com and board settings on arduino are correct and the installer is up to date. I don't think there is anything wrong with my bootloader as I can upload twice at the beginning. Since I'm new to this I would appreciate it if you could go in to detail about how to solve it. Thanks XD
Select proper arduino board form
Tools->Board->

Reinstalling the IDE worked. Thanks for your help.
burning the bootloader helped for me
