Maya ART tool gives "performGpuCacheExport.mel" error

I have the same issue here except also this error when maya starts up:

Error: 2

Traceback (most recent call last):

File “C:/Users/ac/Documents/maya/scripts/MayaTools/General/Scripts\customMayaMenu.py”, line 249, in p4ProjectMenu

f = open(mayaToolsDir + “/General/Scripts/projectSettings.txt”, ‘r’)

IOError: [Errno 2] No such file or directory: ‘C:/Users/ac/Documents/maya/scripts/MayaTools/General/Scripts/projectSettings.txt’
