The size of the code does't matter - it is just used as a unique reference (we have several caches with six letter codes in our "Special" section). The cache has to be in your FOUND database (the database that is selected in FSG for found caches). If it is in the database selected for your found caches, try going to the cache page and downloading and loading the GPX file again to insure that all of the information is present. If that doesn't work, try Database>Repair/Defrag.
