Thanks for the heads up! Should be fixed with 2.5.29.

Great! Thank you, will test - is it safe to install new client 2.5.29 MSI over previous version or better uninstall first?

2.5.29 MSI installer actually refuses to install unless previous version (2.5.28) is uninstalled manually first.

Actualy .exe version works OK without uninstall (tested for Windows 10).
