R: NA/NaN/Inf in X error

Question

I am trying to perform a negative binomial regression using R. When I am executing the following command:

 DV2.25112013.nb <- glm.nb(DV2.25112013~ Bcorp.Geographic.Proximity + Dirty.Industry +
                Clean.Industry + Bcorp.Industry.Density + State + Dirty.Region +
                Clean.Region + Bcorp.Geographic.Density + Founded.As.Bcorp + Centrality +
                Bcorp.Industry.Density.Squared + Bcorp.Geographic.Density.Squared +
                Regional.Institutionalization + Sales + Any.Best.In.Class +           
                Dirty.Region.Heterogeneity + Clean.Region.Heterogeneity + 
                Ind.Dirty.Heterogeneity+Ind.Clean.Heterogeneity + Industry, 
                data = analysis25112013DF6)

R gives the following error:

Error in glm.fitter(x = X, y = Y, w = w, etastart = eta, offset = offset,  : 
  NA/NaN/Inf in 'x'
In addition: Warning message:
step size truncated due to divergence

I do not understand this error since my data matrix does not contain any NA/NaN/Inf values...how can I fix this?

thank you,
