Hi guys I'm brand new here, hope this is the place to post this.... I bought the crj-200 , I beleive it was the 1.4.0 it worked fine, I updated to 1.4.1 and everything seemed to work fine. After I installed 1.4.2, it seems something has gone wrong. After loading I get a message displayed over the view that reads : " error loading navdata or magnetic " nothing in the plane seems to work, there is no power. When flipping the main battery nothing happens, all displays are dark, and most switches do not function. This occures with both "cold and dark" and engiens started. I have been trying to search this out and looking at the topics here but, no one seems to have the same problem occur. I have uninstalled and reinstalled the aircraft, and have no clue to what may have occurred. Any one have any Idea. Every other aircraft seems to function normally. Thank you Jer
