Hello, first post here so maybe it will be stupid.

The thing is, I got 5 antminers s5 mining in antpooll in pplns mode, but just for fun I got a really old pc (2005 amd laptop)doing solo Mining (my energy is free so don't worry), I'm using antpool solo with cpuminer , on the saturday i got a a weird surprise

Of course that I didn't get any money or I won't be here asking for an explanation
next day I got the following

[2015-08-23 04:07:06] Stratum requested work restart

In case you were wondering this is the command I use to run cpuminer
"C:\miner" minerd.exe -a sha256d -o stratum+tcp://stratum.antpool.com:3333 -u MYUSERNAMEFORSOLO.1 -p 123

What's kind of weird is that in solo.ck.pool I had never got that message. So please could anyone explain why my laptop hates me and plays with my feelings??? 50 BTC means that  have my food and expenses for more than 5 Years XD or that I could grow my farm really fast.
Thank  you guys in advance for all your kind help
