Virus B Indigo Problem

I'm currently having a problem where every time I turn on my Virus Indigo, it reinitialises all the presets, meaning there is no point me saving any changes I make to patches. Has anybody ever had this issue? Would it be worth reinstalling the software, or is it a sign of the Battery dying?

Any help would be greatly appreciated.

Thanks in advance.

James.

Thanks Marc, I'll get the battery replaced and touch wood this will solve the problem.

All the best,

James.
