Previously accessible file is now inaccessible

Hi,

I'm trying to run my code, but I'm getting this error:

Error using connector.internal.autostart.run Previously accessible file "D:\Program Files\MATLAB\toolbox\matlab\strfun\num2str.p" is now inaccessible.

For some reason it is being impossible to convert number to strings. I already try to seth a path to this directory, but nothing has worked yet.

I had similar problem. The following command solved at my case

rehash toolboxcache

Maybe your TEMP environment variable is a problem?
