Hi Henrik My Propic used to work fine with th C74. I did have a few problems though, I kept getting error at mem 0 errors the problem turned out to be the vpp section of hardware, the transistor kept blowing. Check your vpp2 voltage with the "set voltages" option in the software to make sure it's at 13v. I ended up throwing my programmer away and buying a picstart plus, but I think my programmer didnt work reliably because of the way I constructed it (with veroboard). Anyway goodluck.
