昨天，我运行了 MikTEX 2.9 的更新过程。由于某种原因（我不知道为什么），该过程异常终止，并且此后 MikTEX 无法访问（每次我运行 latex 时，系统都会说缺少一些 DLL）。我不得不从头开始重新安装 MikTEX...问题是，安装后出现以下错误消息
C:\Users\amarg\AppData\Roaming\MiKTeX\2.9\tex\latex\txfonts\txfonts.sty:128:
LaTeX Error: Too many symbol fonts declared.
显示在日志文件中。此外，对于 txfonts.sty 的某些行，错误
LaTeX Error: Symbol font `largesymbolsA' not defined.
出现了，但我确信这是由前一个错误引起的。在安装 MIKTEX 之前没有出现这些错误，并且 txfonts 包加载没有问题。该错误不会造成问题（据我所知：我没有注意到任何错误），但我想解决这个问题（请注意，如果我注释掉 \usepackage{txfonts} 行，章节的分页就会发生变化）... 看来我拥有最新版本的 txfonts 包，我猜想 MikTEX 安装可能加载了其他包的早期版本，这些包与 txfonts 冲突并导致此错误。我该如何处理这个问题？
如果有帮助的话，我已将 \listfiles 的输出粘贴到下面（我编写了第 26 章）
