[ERROR] Found 1 prepared transactions! It means that mysqld was not shut down properly last time and critical recovery information (last binlog or tc.log file) was manually deleted after a crash. You have to start mysqld with --tc-heuristic-recover switch to commit or rollback pending transactions.
Open cmd and type:
mysqld --tc-heuristic-recover=ROLLBACK
or
mysqld_safe --tc-heuristic-recover=COMMIT
