keeping database Mac (4.8) and Windows (4.7) in sync

Hi, 

right now I'm using the same database on a desktop windows pc (at home) and a mac outdoors.

Worked fine until Basecamp Mac got updated to 4.8 and I was wondering why my data didn't show up in windows.

Today I found out, that the database folders were the problem. 

Windows accesses 4.7 while Mac uses 4.8.

So the only solution is copying everything manually between those folders (which is no nice way syncing it).

Any knows better solutions for this? Or when will the Windows version be updated to 4.8?

I also tried downgrading the Mac Basecamp but it wanted to upgrade again before running.

Cheers
