ExpanDrive 2.0 unreliable in showing (copying?) files

ExpanDrive 2.0 has some very annoying bugs (I consider figuring out how uninstall it and reinstall 1.x). a) Sometimes it simply does not show files that are clearly there (ie, ls sees them). Sometimes a whole folder is empty. Re-mounting the drive apparently fixes it, but I don't feel I can be sure that it really shows me all files.
b) Opening or copying a file from a server sometimes fails with an obscure error ('could not be completed, error 43 or something')
c) I am getting weird compilation errors in Fortran on the server (cannot find a file I just copied to the server)
d) It is unpredictable in updating file metadata (eg, modification date), but maybe the OS X Finder is to blame here.
