For any person installing the control software with a International Windows version like Spanish Windows Version:
Today I decided to reformat my control PC and load the latest software. I installed Windows XP Spanish (because is the license I got with that machine)
After all the installation steps I had the error message: 'Overflow' every time I tried to move any axis.
The solution was to change the regional settings to ENGLISH (UNITED STATES) and it worked just fine.
Hope it helps anybody down the border.
