Thanks for the response. Here are the files you requested.
RedDog- As for upgrading the roms, I simply copied the new roms into the directory replacing the old ones. I'm sure I was supposed to use clrmame or something, but that's super confusing and I'm apparently not adept at finding all the required dat files. However, the roms I'm trying to run are about 20 or so of the classics like frogger, ms pac, etc. so I'm not sure those would be affected.
DazzleHP- I believe everything is running under admin. As for locations, everything is installed on C: drive. GameEx is located at C:\GameEx. As for security, the computer isn't connected to the net so I'm not using any.
Thanks for the help!!
