Some possiblities...

First, when you start crafty does it say something like this:
EPD Kit revision date: 1996.04.21
found computer opening book file [e:/crafty/release/bookc.bin].
using cpu time
search time set to 9999.00.
Crafty 17.10 vs ferret
pondering enabled.
EGTB cache memory = 6M bytes.
hash table memory = 24M bytes.
pawn hash table memory = 8M bytes.
EGTB access enabled
using tbpath=e:/crafty/release/tb,F:/KBP
4 piece tablebase files found
1302kb of RAM used for TB indices and decompression tables


Crafty v17.10

White(1):

Note (especially) the "4 piece tablebase files found" line, which in your case
should say "5 piece tablebase files found" instead.  One way to control how
crafty finds things is with SET commands like this:
SET CRAFTY_BOOK_PATH=e:/crafty/release
SET CRAFTY_LOG_PATH=e:/crafty/release
SET CRAFTY_RC_PATH=e:/crafty/release
SET CRAFTY_TB_PATH=e:/crafty/release/tb,F:/KBP

Or (better yet) use control panel to set them up.

Assuming you can find and load the tablebase files, find a position that causes
problems.

Are you using multiple CPU's or a single CPU?
