Hi,
When starting IGO8 at my device the starting initialization stops with "Fatal error - Initialization error: LoadLanguage failed".
I tried to change the "lang" library but the problem continues.
Any solution?
Tanks in advance.

delete the save folder is the first thing to do.

I deleted the content of the "save" folder.
The problem continues.
Thanks

The save folder holds the settings and is freshly made after deletion, so it can be deleted completely, not only the contents.
It doesn't help? Did you make any changes or is this a new install? The lang folder is in the content folder? The language files are unzipped? Where is the foder located, on SD or internal?

I updated maps so it means making a change. The lang folder is in the content folder. The language files are zipped. All IGO and its folders are located in the internal of the device.
I have a second (same type) device with the same IGO which works ok.

Finally some one who answers all questions and above all, as complete as possible. Not all users in trouble do so making it difficult to determine the problems as exactly as possible.

So you have all things twice, device and igo?
On the faulty device, something has gone wrong, either a software (corrupted file)or hardware issue (damaged memory bit or byte).
Since igo is very easy to install again (copy/paste) I suggest to delete the whole faulty igo and replace everything. When the igo on the two devices is different after all, it may be useful to back up the old program and restore the files you want (sys.txt, skin, ..). I hope this method overrides the faulty (hardware) byte when there is one. It sure will correct all software issues.

Thanks, I already deleted the lang folder from device A and copied to it the same folder from device B and the problem did not change.
I hesitate applyng your radical solution; Already copying all Igo files from device B to my computer I am not sure that all the files were copied completely.
Anyway thanks again for your assistance.
