Maintain Dimension Members Error: StartIndex cannot be less than zero

Hi,

I am using BPC 10.0 MS version and Microsoft Excel 2013. I ran into a recent problem when I try and maintain dimension members I receive the following error: StartIndex cannot be less than zero. Parameter name: startIndex.

This has occurred in all the dimensions.

Any ideas anyone can offer to help me resolve this issue?

Thanks for your time!
