Ok I just made a new fresh install of Multiminer with the Win32 that it download normally. I configured it as normal and let it run for a little while in scrypt. I just sent you the files with the results in it by email. As you will see, Multiminer reported a hashrate of 0 all the time i let it run and even restarted at least 2 times because it reported Zero Hashrate. (Because i didn't unchecked the option in the settings) But in truth, you can also see that it WAS working because the accepted shares were pilling up. All those problems goes away with the win64. If you need my files with the Win64 also, just let me know.
This appears to be an issue with the 32-bit version of bfgminer. Both cgminer and the 64-bit version of bfgminer always use US culture info in the API calls. This means even if your current locale settings in Windows use a comma for a decimal separator, the API does not. This makes sense since the API is an RPC API and may be running on a different system.
However, the 32-bit version of bfgminer is returning values from the API calls taking into account the current culture information.
64-bit bfgminer, non-US locale:

I'll talk to Luke about it and see what to do. For now continue to use the 64-bit bfgminer when the Windows culture info is non-US.
