Changing fiscal year in peach tree 2012?

[Galcam]

I have 18 months of data in peach tree 2012. The data is from July 2012 to dec 2013. The fiscal year in peach tree is nan to dec and it should be July to June. I am in period 24 so have to close a year before I can enter data for 2014. What can I do to change fiscal year? I have perhaps 30/40 transactions per month for 18 months. Thanks

Interesting question. What I will do if I can find time is turn a sample company and try changing the fiscal year on that. However, I've seen that as an issue with lots of software.
