Corrupted blocks
On rare occasions, you may get a message as you open a library that indicates that a block has been corrupted or is bad. The corrupted block will appear in the library window as *BAD*Blockname. To save the rest of the library, copy the uncorrupted blocks to a new library and discard the old library. Then copy a backup copy of the block (if you have one) into this new library. This is a good reason to always back up your work!
