Sterling Integrator Map editor issue --- Runtime Error!

Issue :

I got below error while opening the map using map editor

Cause :

I have changed backup file of the map from .BAK to .MXL format and I have tried to open the map but I got error as above.

Resolution :

After changing the format of map , then need to open that map in notepad or notepad++ or any text editing tool. It will be look like as below

Once it is opened then need to save as that map as .MAP format. Then you can able to continue with mapping or testing as per your requirement. You won't loose any existing mapping or coding in the map
