Hi i have got the following error. I had run FRF on the same model (large) previous week for same frequency range. It was fine. This week for another FRF analysis for the same frequency this is showing this error. Please help  

*** ERROR # 2782 ***

  32bit integer overflow occurred in reduced order model processing. This is

  usually because of the higer than default value of AMPFFACT used in analysis.

  If not, it is simply due to too many eigenvalues located in the requested

  frequency range. Reducing the upper frequency bound in EIGRA card is likely

  to make AMSES go through. This issue will be resolved in later version.
