can't compile anything with the latest beta

Everytime I try to compile something I get these 3 error messages:
The type or namespace name 'RateOfChange' could not be found (are you missing a using directive or an assembly reference?) "Pcnt_Decrease" [Indicator] Ln 16
The type or namespace name 'RateOfChange' could not be found (are you missing a using directive or an assembly reference?) "Pcnt_Increase" [Indicator] Ln 16
The type or namespace name 'PercentChange' could not be found (are you missing a using directive or an assembly reference?) "PcntChg" [Indicator] Ln 17

I installed the latested beta 64 bit.

Please delete the following indicators:

Pcnt_Decrease
Pcnt_Increase
PcntChg

They have been changed to:

Percent_Decrease
Percent_Increase
PercentChg

I also have to delete PcntR and Avg_Close_Greate_Avg_Open. Strangely enough this also happens if I delete the whole CS directory before installing the latest Beta over the initial version.
