GSEA parameters I input are:
1 group, 1 factor with 2 levels
max_probe
5 minimum genes
1000 permutations
msigdb.v2.5.symbols.gmt downloaded from msigdb
annotation already downloaded for affymouse430_2 array

The following text occurs after I execute the GSEA:

Collapsing probes to genes
Reading gene set files
Creating Association Matrix
Removing gene sets that do not pass the minimum genes criteria
Algorithm execution begins...
Algorithm excecution ends...
Generating Viewers...

at which point I get an Analysis Error window. If I click on stack, it says this:
java.lang.NullPointerException
