Run POS for LS Retail Error !!!!

I have a problem for LS Retail when i run client POS, How to resolve it ?3326.pastedImage (1).png

what exactly did you do? what was the last action?

i don’t know customer do something. they ask to me they do not anything.

did the error occur more than one time? did you get the error on a second pos ?

best restart the pos (the client computer).

also contact the support of your nav partner. the error message could be the result of a buggy customization.
