This question already has an answer here:

After I did an update of MikTeX of packages lualatex won't compile anymore.

I tried this solution Why does Lualatex crash after a recent update?, but no luck.

I got this error file:

 Sorry, but miktex-makefmt did not succeed for the following reason:

 miktex-luatex.exe failed on lualatex.ini.

The log file hopefully contains the information to get MiKTeX going again:

Sorry, but "MiKTeX Configuration Utility" did not succeed.

Now I cannot compile my tex files. I use Lualatex because it uses dynamic memory for my pgfplots (a lot of data)

    miktex tried to install the unicode-data package but the installation failed due to the "unknown archive file size". Try to install it with the package manager from another repository. – Ulrike Fischer Mar 7 '16 at 16:26
  • @UlrikeFischer thanks for the answer. Tried that and did not get the error while doing the Build in the MikTEX. I tried compiling a document in TexStudio and got an error about the package ctablestack not found. I proceeded to install this and later I got tons of error referring to fontspec and hobsub-generic.sty. Any idea now? – Gabriel Mar 7 '16 at 17:21

  • Great! It seems to work again! The last link did the trick. I had just updated the Admin. Thanks again @UlrikeFischer, I will keep you updated of something else pop up – Gabriel Mar 7 '16 at 18:56
