If so, respond with your email address so I can email you a new revision of Page 22 of the "Rules Cyclopedia". The thieve's skills percentages were rediculous and way out of line with AD&D and every other game on the planet. I reworked the percentages to actually make thieves useful. I knew there was something wrong with them because the thief character in our group is level 7 and has never succeeded at anything other than climb walls!
Just print up the new page and tape it over the old one, it changes the thieve's skills tables and changes text references to match the new numbers.
