Having trouble with FPGA(Altera DE2 board) mining

I've been trying to mine with a DE2 board, and it keeps giving me this error
ERROR: Unable to getwork. Reason: key "result" not known in dictionary.
Anybody have any idea why?
I'm using The Open Source FPGA Bitcoin Miner
I have a regular DE2, not a DE2-115, and I managed to get the correct sof file to set it up (can't remember where I got it from though), so that's probably not the problem here..
I've tried using the mining_proxy, as someone suggested on the same fourm, but I can't seem to get it to work at all.. In fact, I have no idea how I was supposed to make it work; I even tried the proxy with my GPU and still couldn't get it to work.
the .bat files I used were
mining_proxy -nm -o -p 3333
cudaminer.exe -o http://localhost:8332/ -O username:pass
Maybe if I get this working correctly, it'll actually work this time?
It would be awesome if someone could help me out here, I don't know much about mining in general as I started out only yesterday.
Thank you in advance!

The compile the code on an different Altera device then DE2-115, you need to set the Device to be the correct one. Find the correct FPGA package number and add it, for the DE0-Nano this is EP4CE22F17C6. Be sure to select the correct one, because the hardware effects the location of your pins, which you will need in the clock pin step. To get the provided code to compile on a smaller device ...

Field Programmable Gate Array (FPGA) ist ein integrierter Schaltkreis, der vom Kunden oder Konstrukteur nach der Herstellung konfiguriert und somit "feldprogrammierbar" ist. FPGAs sind integrierte Schaltkreise, die nach ihrer Herstellung für eine bestimmte Aufgabe, wie zum Beispiel für den Mining von Bitcoins, angepasst werden können, wodurch ASIC entsteht.

FPGA Bitcoin Mining. At the foundation of block creation and mining is the calculation of this digital signature. Different cryptocurrencies use different approaches to generate the signature. For the most popular cryptocurrency, Bitcoin, the signature is calculated using a cryptographic hashing function. For those unfamiliar with cryptographic hashes, hashes calculate a fixed-length unique ...
