Ok, I figured out that DA version 1.8e had the problem with fleets not being able to be assigned destinations much more than one turn's worth of movement points. I also realized that this was presumably fixed in version 1.8q. The problem is that my computer doesn't update to 1.8q via SDC--it still reads 1.8e.
I also realize that there is a post regarding a regedit fix, involving changing a "version string" to 1.7.
I don't know what a "version string" is, and I don't want to manually edit my registry, unless my computer is dying.
Is there any fix from the standpoint of SDC for this problem, without my having to enter my registry?
