Anyone else having a problem with Protoshares windows program shutting down? I get a visual C++ error popup 2-4 times/day and it says something about protoshares shutting down for unexpected reason, and to notify software developers of problem?

{
"blocks" : 3101,
"currentblocksize" : 1000,
"currentblocktx" : 0,
"difficulty" : 0.00000095,
"errors" : "",
"generate" : false,
"genproclimit" : 3,
"hashespermin" : 6.62893900,
"pooledtx" : 0,
"testnet" : false
}
I am running an Intel i5 with windows 8, 64 Bit OS and 8 GB or Ram.
P>S> I also saw suggestion to run multiple instances of program, if enough memory available, but when I try to start 2nd instance, I get error message and 1st instance shuts down immediately, Anyone been able to multi-execute successfully?
