Atmega 328P with AVR Pocket Programmer

I am working on a project (first major DIY project) in which I designed a board and soldered parts onto it. This includes the Atmega 328P which was bought in bulk and should be without a bootloader. The board is similar to Nootropic's designs hackvision and is essentially a TV Out based Video Game Console. I am using both Composite A/V and VGA Out (using Nick Gammon's setup and libraries.

I used to work on this project this past summer in a Lab where I used an iMac for most of my Arduino code. Now I am looking to continue this work at home with PCs but am not able to interface with the Microcontroller. I use the AVR Pocket Programmer and a 6 pin header on my board. I am fairly confident all my connections are correct. The Arduino IDE just neglects to recognize that there is anything on the USB port giving me "USBtinyISP not found". I tried researching a similar problem everywhere and downloaded some drivers that did little to fix the issue.

I am really inexperienced with this AVR Pocket Programmer and have little idea about how it works with the Arduino IDE. All I know is that it used to work with OS X and I really need to get code uploaded to the Microcontroller to finish my project as a demo.

Any help would be appreciated and there is a link with the schematic and board files i thats helpful.

Sorry this is rather non-specific to Arduino but more Windows+Hardware in general stuff. You didn't say in your post that you checked this specifically, so I figure it's worth posting & trying.

I'm assuming you've got this thing? - Pocket AVR Programmer Hookup Guide - SparkFun Learn

If you open device manager, does it show the a USBTiny under LibUSB-Win32 Devices?
Is there anything showing as having no drivers or some other problem?
Can you try plugging a flash drive into that USB port, just to verify the port is still working correctly and hasn't been damaged?

The Sparkfun page says that they had a download for drivers that didn't work under Windows 7, and to download their new ones. Maybe give those drivers a go.

Cross-post - please reply to the other thread.
