Ugh.
I am in no way a computer techy at all. I know about nothing about computers except for how to use them, how to talk to ppl, and how to build roller coasters through NL and Elementary and all that yummy stuffz. For some reason my newest coaster Stream Line is having some DL issues (or whatever it says). Now, what I have done in past years when I get that message is try to reopen the package manually. In other words, go the the Track Packager, and click File, and then Open Package, and then click the package that you would like to see. If that doesn't work, then I need somebody to help me fix this problem. Again, I don't know much about computers... NEWB ALERT! hehe...
PM me if that doesn't work for you.
