[NEWBIE] Can't connect to the pool

Hi guys,

I try to join the pool, but I experience some problems and I require some help.
This is probably VERY newbie questions but I’m not familiar with mining.

I was reading your tutorial https://ethereumpool.co/how/
As I’m running Win10 with an NVIDIA Quadro K3100M card, I downloaded cudaminer and extract it. I extract it on my HDD, I hope it’s not a problem.

Then I edit eth_pp_ua-cuda.bat file, it looks like this :

ethminer -U -F http://pool.eth.pp.ua/?miner=10@0xE318929E8bDF5a8A726927BcB9aa7eE3bc2CcaC0
(I replace the address by my own address 0x...)

I have no idea what is the « Optional Rigname », so I removed it as it looks like « optional ».
Then I run eth_pp_ua-cuda.bat file, and it seems it is looping on the following error :

Failed to submit hashrate.
Dynamic exception type : class jsonrpc ::JsonRpcException std ::exception ::what :: Exception -32700 : JSON_PARSE_ERROR : The JSON-Object is not JSonValid : Database Error


So I take a look about hashrate (I’m not sure what is exactly is – yes I’m a VERY newbie) and run ethminer -G –M but the result is :
Trial 1... 0
Trial 2... 0
Trial 3... 0
etc etc...

So, could you explain me what I do bad, and how to correct it ? Thanks a lot guyz J
