Caused by the language setting for Windows. Specifically the problem relates to having a decimal point separator which is a comma “,” as opposed to having a period “.” which the applications were written to work with. The applications are being modified to handle this in future releases but in the meantime you will have to either:
a) Set the Regional and Language Options to be some English flavour
Or
b) Customize your current setting so that the decimal separator is a period “.”
Do this from the Regional and Language Options in the Control Panel for Windows.
You will need to re-import all your data once you have changed the settings.
