Look at the journal/logs, it should be written something there.
Besides, you can search EAs in Metatrader: type the name of the EA on the top right corner of Metatrader.

How to Install an Earlier Purchased Application

Hi all,
I have purchased 2 EAs directly from MQL5.com but stopped trading for awhile. My VPS account has been cancelled and I have installed a new OS on my PC.
The seller had decided to stop selling those 2 EAs. I have saved copies of the 2 EAs but they don't work when I attached to a chart. The other EAs are working just fine (just those 2 from that developer)
The developer advised me they are standalone EAs and should be working. I think they need to be activated again with new platform, right?
Can anyone show me how to do this or get these EAs working again as that's a big sum of money? The cost of decompile these 2 EA are too high
Thank you for reading
Regards
Kevin
