Desktop version crashing with Yosemite

I have just downloaded the desktop version off of your site for MAC so I assume that his would be the latest version.

I am impressed with the system but I am experiencing the program crashing at various times when opening and closing and randomly when changing screens within the program.

Are you able to offer and advice before I jump in with our business data.

Do you get any error message when the program crashes?

No it would appear not, it just closes the program with no warning ?

Create a new user account on Mac and try to run Manager from there.

I never had any problems with my 2 Macs.
