If your QuickBooks Premier™ Desktop file keeps crashing, throwing error codes like -6000, -6190, or H202, or slowing to a crawl, you’re not alone.
Corruption and instability in Premier files often sneak up over time — especially in multi-user setups.
Here are the 10 most common reasons your file keeps breaking, and what you can do about them before it turns into a disaster.
🔹 1. Oversized Company File (Over 250MB)
QuickBooks Premier isn’t built for bloated files. When your .QBW file crosses 250MB:
Reporting slows
Backups fail
Rebuilds don’t complete

🔹 2. Improper Shutdowns or Forced Restarts
Closing QuickBooks using Task Manager or power cuts can scramble indexing.
Always use File > Exit and wait for the auto-save to finish.
🔹 3. Multi-User Mode Misconfigurations (H202, H505 Errors)
If QuickBooks can’t communicate across the network, files may lock, crash, or not open at all.
Fixing this requires:
Checking hosting settings
Verifying firewall rules
Resetting QBDBMgrN services

🔹 4. Too Many List Entries
QuickBooks has hard limits:
14,500 customers/vendors
10,000 items
250 custom fields
Exceeding them breaks reports and freezes the file. Use File > Utilities > Condense Data to trim history.
🔹 5. Corrupt Attachments or Logos
Broken image or PDF attachments in forms can corrupt templates.
Avoid copying-pasting from Word or Outlook — and always test new templates before using them in bulk.
🔹 6. Outdated Version or Patch Level
Running an outdated version like Premier 2020 or skipping updates can cause:
Broken tax forms
Compatibility issues
Security gaps

🔹 7. Network Drive Syncing Tools (Dropbox, Google Drive)
Syncing your .QBW file across cloud tools causes double write conflicts, even if you’re the only user.
Always store your active company file locally or on a dedicated server.
🔹 8. Damaged .ND or .TLG Files
These tiny index files do a big job. If corrupted, they can prevent your company file from opening entirely.
Delete them (QuickBooks will auto-generate new ones), or call Biziblaze to do it safely: https://biziblaze.com
🔹 9. Running Payroll or Large Reports in Multi-User Mode
Some operations — like rebuilding, payroll runs, or 1099 creation — work best in Single-User Mode.
In multi-user, they often crash or hang due to conflicting memory calls.
🔹 10. No Routine Data Verification
If you haven’t run File > Utilities > Verify Data in the last 90 days, you're overdue.
Silent corruption builds up — especially after imports, custom fields, or template edits.
