MT4 Portable problem

 
Hello
I have a problem with MT4 Portable / build 1260 /. When I change my computer, the EAs and indicators from the mql store don't work. There is a message in the log:
MQL5.chats: deleted due to security reason

There is a record in the experts entry:
  cannot load 'E: \ MT4 \ Portable \ MQL4 \ Experts \ Market \ Manual Trader.ex4'
and
cannot load 'E: \ MT4 \ Portable \ MQL4 \ indicators \ Market \ SFX ATR Dashboard MultiPair.ex4'

I need to delete the EA / Indicator and download it again from the store. This loses activation. Can you help me, please? Thank you very much
