When i try import tide station csv file nothing happens, but this file successfully imported in RM 1.8. I check the format in help file and it is correct.
All this done in new workspace.
Please see attached file.

Thanks.
I don't get an issue importing that file - I see 39 points imported, shown in the status bar at the bottom of the main window.
What settings are you using to import? UTC or local time? Metres or feet?

I am using default setting. UTC,metres in demo workspase. it was tested in two PC win 8.1 x64 - work as expected , win 7.1 x32 - not working.

I am pushing the Import button, choose file, and seeing screen bellow

Thanks for the extra information Gregory, I will investigate further.
What localisation settings do you have on the PC that is failing?

i located the errors area. If i set format in regional setting English(USA) -import work fine, but if set Russian(Russia) it doesn't. Maybe RM waits file with format from regional setting?

I will look into this Gregory, it should be able to handle either, so long as the format is correct in the file.

fixed in release 2.0.25.0
