Windows 7 64bit  CPU mining.
Cointron LTC mining

I've been using minerd.exe and mining_proxy.exe with the following commands on my main system and it works with no problem:

c:\ltcminer\mining_proxy -pa scrypt -o coinotron.com -p 3334
c:\ltcminer\minerd -a scrypt -r 1 -t 2 -s 6 -o http://127.0.0.1:8332 -O (my user name).1:1
(my user name - what i registered with but not shown).

I've recently diverted work to the laptops and freed up the main system for BTC mining.  On my laptops I'm not always getting the results I want. (using different workers btw)

For the first couple of times it shows the following: accepted 1/1 (100%) <yay!!!>   then  2/2; 3/3 up till about 4/4.  At that point, it starts showing this:  JSON-RPC call failed: {"message": "Unexpected error during authorization", "code": -1   json_rpc_call failed , retry after 30 seconds

After that, it begins to hash again and shows LONGPOLL detected new block, but the <yay!!!> have stopped appearing and the cointron dashboard shows the work has stopped  (0kh/s).

What do you suppose causes this?  Tried looking around, those who had similar issues were using 3333 port instead of 3334, but I'm definitely using 3334, plus I was getting working results for the first couple of runs, then it craps out and the work comes to a halt.

Did you solve this? What was the problem?
