I have released another beta which fixes one serious issue and improves errorhandling a bit.
This bug is present from the moment the cost entries were added. The last day of a period would be excluded and give no money at all. ( Thanks Graham for finding this one ).
Solution: Update the jar file and use -updatecosts. This will recalculate all the costs.
When no data could be loaded it would end in a serious exception crash which was pretty cryptic. I have modified this and added a neat message that no data could be loaded. Including a few pointers how to fix this.
I consider this release as stable, so anyone who are using 126.96.36.199 can safely update to 188.8.131.52b2.
Another release soon
