I am using samba 2 and reports wont load anymore

Hello I am currently running POS 2 ( I think)  "C:\Program Files (x86)\SambaPOS2"  I have everything set up the way we like it so I am hesitant to upgrade to v3 I really do not want to loose all the work I have put into the program the last 2 years.  When I started using the program the reports feature worked perfect for item sales work periods ect. but now my reports wont run at all any help would be appreciated.
