Debug and Fix Non-Functional MetaTrader 4 Expert Advisor

JOB DESCRIPTION:

I own an Expert Advisor (.ex4 compiled file) that worked flawlessly for 3 years but stopped functioning on May 13, 2026. I need technical help to restore it.

THE PROBLEM:

The EA displays this error: "GoldPrime: Invalid license. Removing EA now."

The original developer has ceased operations:

• Website offline since mid-2026
• Support unresponsive since March 2026
• Product appears abandoned

I legally own this EA With 2x lifetime licence (Order ID on file, proof available). I simply need it restored to working condition.

WHAT NEEDS TO BE DONE:

Analyze the .ex4 file and restore its functionality. The EA must: ✅ Resume normal trading operation ✅ Execute all original buy/sell signals without errors ✅ Apply original stop loss and take profit logic ✅ Work on any MT4 broker at least on demo account  ✅ Maintain 100% of original trading strategy ✅ Be fully debugged and tested

WHAT I'M PROVIDING:

You will receive:

• Complete Gold_Prime_2.0.ex4 file
• All associated library and dependency files (.ex4, .mqh)
• Exact error logs and screenshots
• Proof of legal ownership (Order ID)
• 3 years of successful backtest data for reference
• Detailed description of what's not working

EXPECTED OUTCOME:

The EA should work exactly as before:

• Same trading signals
• Same risk management
• Same timeframe (XAUUSD)
• Same broker compatibility

PROJECT DETAILS:

• Budget: +200$ (fixed price, negotiable based on complexity)
• Timeline: soon as possible
• Testing: Full demo account testing before delivery
• Deliverable: Working .ex4 file, ready to trade

IMPORTANT NOTES:

This is legitimate technical restoration of software I legally own. Not a request to crack commercial software or violate intellectual property. The original developer is defunct; this is a restoration project for abandoned software.

I can provide:

• Original purchase confirmation
• License ownership proof
• Error logs and screenshots
• Full transparency on the project

SKILLS REQUIRED:

• Expert-level MQL4 knowledge
• Experience with compiled .ex4 file structure
• Ability to debug and troubleshoot EA code
• Understanding of MT4 internals and functionality
• Experience with legacy software restoration
