Timeline in Premiere Pro CS4 Issues

Hello,

I have a refurbished Dell Optiplex 9020 with the 4570 Core i5 processor and Windows 10 pro, 16G of RAM and a 120G SSD drive for OS/program for the most part and picked up a 500G HD for file storage (currently only video clips) and for the scratch disks and eventually will pick up a 500G or larger SSD drive. The graphics card is the Invidia Gforce 610GT with a gig of memory onboard as it was what I brought over from my old Dell Studio XPS PC I retired.

The old Dell PC had Vista, then for a brief period, Windows 7 before aging components, a failing hard drive and the OS becoming unauthorized and would soon be obsolete anyway by next January lead me to upgrade to the Optiplex running Windows 10.

While on the old Studio XPS with Win 7, I was revisiting Premiere Pro for the first time in several years as I had no good way to import analog footage to the PC since I never got a capture card and when I had my stand alone DVD recorder to use as the intermediary for importing said analog footage, it worked great under Vista. So in January, bought a second hand Canon Vixia HF R500 AVCHD camcorder from a local pawn shop so I could begin to make inroads to setting up my YouTube channel in the hopes it can become a revenue maker eventually and by this point, had Windows 7 and the Master Suite CS4 and it worked great, though I did have an issue with the timeline acting up then too but found a solution and got it back up and running but have since replaced the old Dell with the Optiplex and it had been working, but apparently even though I told Windows 10 NOT to update, it did anyway? So now Premiere's timeline is all wonky again and am not finding the solution to solve this. BTW, if I double click on the sequence file, the timeline restores, but goes right back to being wonky the second I try to move a clip to it.

Essentially, when I move a clip, be it A/V or audio only, doesn't matter, the timeline that looks fine suddenly gets overlaid by what appears to be another timeline and off centered so I can't drop clips where they need to be and causes issues.

I've restarted Windows, turned off all programs outside of Premiere, same thing. Even opening up another project I had begun has the same issues. I had a solution to this at one point but have since lost it and my Google kung fu seems to be coming up with partial or no solutions in the past 24 hours.

Any ideas on what to do? BTW, I have Vrs 4.0 of CS4 for Premiere.

Thanks!
