Hello
I have some problems when importing sl2 files.
Some files are ok and some not.
If I open the faulty ones in Lowrance Sonar Viewer, they sems to be fine.
The message that appears says "application error" a number that is not negative is required.
Se attached image in swedish.

Hi Virre,
Could you please zip one of the problem files (the smallest) and upload to a file share service (eg http://www.sendspace.com/) and send the link on to This email address is being protected from spambots. You need JavaScript enabled to view it. .
We will take a look.
In the mean time, you can try using the slg2txt application instead, which will allow you to import just the depths/location (no sonar viewer). Select the option "UseSLG2Txt" in the gps profile, and then locate the slg2txt.exe application in the global settings.

thanks,
Matt
