Hi Horst,

If you have a file that opens in 2015 and not in 2017, please send it to me for testing right away, as that would confirm a verifiable bug that can be reported and fixed.

The file I've received from you so far was badly damaged, and won't open correctly in any version of RealBand (I tested this thoroughly). Unfortunately, if files are getting that badly corrupted somehow when being transferred via DropBox, that's not something that's within our power to fix, but if you have files that work in some versions of RB and not others, that's a different story, and definitely something we can deal with.

Thanks
Kent
