Minecraft Internal Error?

[andersad]

       Minecraft works just fine at my Dad's house(parents are divorced), but the problem is, every other week I go over to my mom's house. Minecraft never seems to work there. It says,"would you like to update minecraft?" When I click yes it says: Internal Error, Could not update. This really gets me mad because I love to be on opti and I hate spending some of my weekends without Opti, let alone minecraft. Please post on here is you you know how to fix this problem I am having.

This should be posted in Support under SMP, not Server Software Support.

And I don't know how to fix this, sorry.

Try running it through Adminstration mode by right clicking on the .exe file.

Or enter this in the Computer dir bar and delete the '.minecraft' folder: C:\Users\changetoyourusername\AppData\Roaming\.minecraft\
Then re-download minecraft.exe file to regenerate the folder and see if it works.

Not sure if these work, but at least you're trying.
