offset < 0 with rmap files

[soad]

Hello,

I have converted rtmap files to rmap.
When i load this map i have the error :  offset < 0 : ....

How can i could solve this error ?

Best regards,

Try the tool in the menu. Maps > recalibrate map

It doesn't works. It's seems recalibrate map tools only works on the current map and i can load the converted rtmap.
