Importing indicator corrupted other indicators

[BReal]

I attempted to import the CCI Moving Average indicator from the indicator library and it succeeded. I didn't like it so I deleted it and now I've got several errors when trying to compile another indicator regarding about ten other indicators. The error says "NinjaTrader.Indicator.SMA is a 'type' but is used like a 'variable'. I don't know what other information I can give to be helpful. Please HELP! Thanks in advance.

I may have overwritten the SMA indicator with an older version from the indicator I downloaded. How can I find / revert to the current version of the SMA indicator?
