Might want to invest in an XO controller. Will make your life much easier.

or Xbox 360 controller for a cheap XInput controller. or DualShock 4 (Bluetooth and microUSB required) for both DirectInput and XInput (With DS4Windows or InputMapper) support and the sixaxis, with touchpad serving as a mouse.

And that's good. Time to get rid of the old cruft already (they don't maintain the old code and that's where most of the goddamn security vulnerabilities come from, some things they can't patch because it would break compatibility and that's a big no-no).
They should make something like Windows XP mode was for Win7 for people with old and unsupported stuff.
