primo 2.4 error

I have primo 2.4 installed on my chinese 2 din with wince 6 and all seems to be working well except when I need to edit a route. I go to avoidances, select the road I need to avoid, and get an error notice and the program closes. Anything I can do to fix this ? There are times I need to avoid a proposed turn in order to take a later turn or continue the road I am on before the proposed turn for a bit to avoid traffic congestion. The program is chas521's english version with North Carolina USA 2013 map. Thanks for any input which may lead to a solution !

I dont have confidence in that 2.4. I was trying it out and it was telling me the wrong street signs and the wrong speed limits. I just gave up and went back to igo8 what i have never had a problem with.

What's old is what's new. More often than not is much better also.
