Cannot build Genetree using WGCNA

I'm trying to using WGCNA to analyze the TCGA Database to to build up gene-co-expression network. I have downloaded the BRCA__gene.normalized_RNAseq__tissueTypeAll.txt and input this into WGCNA. But when it goes to

geneTree = flashClust(as.dist(dissTOM),method="average");

It shows

Error in hclust(d, method, members) : NA/NaN/Inf in foreign function call (arg 11)

Anybody knows how to solve it? Thanks.
