For 10 yeras i had been using ws 2350, heavy weather (HW) and wswin ... last week i started using davis vantage pro 2, weatherlinK (WL) and wswin. All has been running smoothly, except one thing: all data obtained by HW are suddenly gone - there are no graphs for the past in wswin - just the newer ones from WL. When I open "weather - statistic dates" in wswin, there are some yearly data for the past, but none monthly data.
Are my wswin data (graphs) for the past permanently gone or is there any chance to restore it and how?
Please help me if you have any idea, because i am panicing a bit, beacuse i dont want to loose 10 years of data.

Thank you!
